It’s a really complex case. “Marianne is so intelligent, she wouldn’t have drowned.” But if she was so intelligent she wouldn’t be dating him and doing this amount of drugs and alcohol.

WOW. He walked away from a police officer and had time to go into his house and write a suicide note . This entire situation is unbelievable

"I know my sister, she wasn't a careless person. "... omg, your sister is doing all kinds of drugs and partying, that's pretty careless

She wasn’t careless, she was a responsible woman. Really? She was sleeping with a known drug addict at his home, mixing different drugs all while drinking alcohol. Moral of the story, be responsible and carful who are associated with, and don’t do drugs!

Moral of the story: don't do drugs

So if one is intelligent they can't drown? That woman is unbelievable!

The best lesson to take from cases like this is to be careful who you surround yourself with. ESPECIALLY if you’re going to engage in risky &/ or illegal behavior. If you’re dealing with an ex con who’s on parole, there’s a high likelihood that if something happens to you, they won’t call 911 asap.

Legit I kindda hate the sister. She says over and over that her sister was so intelligent she would never drown in a hot tub. Like what? Only stupid people drown in hot tubs? Or drown at all? Her sister was so intelligent she was married and divorced 3 times before the age of 30 and did drugs in the woods with hippies. That's how intelligent her sister actually was.

Props to the sheriff for being honest about not following policy

I still think that this was an accidental death, the 2 dope heads panicked and it looked like they were trying to cover up.

That is the scariest statement in this whole story, because it is far too common. "I had my mind made up and nothing they were going to tell me was going to convince me that Marcus didn't do it". Jurors admitting they don't even care what the evidence says. Thank God she eventually listened. What happens in cases where the evidence isn't overwhelming? Or it's not as clear? An innocent person goes to prison.

I feel very sorry for the sister, but she consistently buries her head in the sand about Marianne's actions.

Pretty haunting to see Clark’s last moments on earth

Intelligence does not mean one has wisdom or common sense. Hard drugs and alcohol should never be mixed.

Interesting how the sister of the deceased says ‘my sister is not a careless person,’ yet there she is doing Ecstasy at the age of 40-50 years old….

"I know my sister wasn't a careless person" Dates drug addicts, hangs out with other drug addicts, goes bar hopping, does drugs.......

It was a weak case. I'm not even convinced that this lady was even murdered at all. The best they could have tried him on was failure to contact authorities in a timely manner.

Makes me mad when the sister implies smartpeople wouldnt drown!! If she was so smart why did she go in a hot tub while under the influence? But its an odd one and hard to know what happened. Im sure the people there didnt really know as they were not sober enough to.

That professor’s poor judgment, heavy drinking and drug use ended with her death. Such an appalling horror story.

The Son, the young Man who cautioned the dead Lady about his Father shows very good character and the most sound judgement of the lot. I respect him for his courage to warn her. Too bad she did not head his warning, she lacked his good judgment. She made many poor choices even if she was "bug smart".

The jury got this right. Whether Marcus killed this woman or not we will never know but the law states in order to convict it must be "beyond a reasonable doubt". The moment Clark walked back into his home and blew his head off is the exact moment "reasonable doubt" was established and by that action alone, the jury must acquit. The law is the law.

She wasn’t a careless person? She drank a lot and took ex.

I actually do agree with the jurors. There was way too much doubt in this case. I actually do believe that Marcus didn’t even know what happened because he was so high on Coke 😕 They all were, and it would have been really hard to find out what really happened 🤷🏻‍♀️

If I heard this was an intelligent woman one more time I would throw up in my mouth a little bit. It is one thing to be to doing heavy narcotics in your twenties (not smart, but everyone has there own self discovery), it is another to be in your mid 40s doing these drugs with a self centered narcissist. Being able to catalog insects does not make one intelligent. I think the verdict was correct, all they had were women that had aggressive sex with him who kept coming back for more. The guy blowing his head off was enough reasonable doubt, surprised they even brought this to trial.

I would like to know the conversation between Clarke and Marcus in the 2 hours before calling 911.

This case has stuck with me because there are way more questions than answers in regards to this case.

The sister kept saying how smart Mary Anne was. Well sorry but doing drugs and drinking while around water doesn’t sound like the most intelligent woman in the world. She sounds like she lived a wild life 🤷🏻‍♀️ I’m not saying she deserved to be killed but she def lived a life in the edge

"If she was so scared when I was choking her, then why didn't she say anything?" BECAUSE YOU WERE CHOKING HER!!!

I agree with the jurors. A man killed himself when police arrived and started asking questions for goodness sake! This guy may not be a model citizen whatsoever but I am thankful that unbiased jurors went only by the evidence presented. That being said, her death is tragic and I’m very sorry for her family.

"I gave it to my dad" and he burned it? How convenient

Honestly, that was my first thought - it wasn’t a homicide. No one did it.. absolutely could of been from the ecstasy (which dehydrates you significantly) and being in the hot tub, drinking and THEN having a health concern/heart issue as well. Also, waiting too long to call 911.. maybe they could have saved her, maybe not. We will never know. It was a unfortunate combination of bad choices and circumstances. ✌🏼

You think a professor should be smarter than letting individuals like this in her life!!

"Just a little pressure on them carotid arteries..." Lol. That's gold.

Whenever you hear descriptors like, “charming, charismatic, etc” it usually means they are narcissistic con artists. Unfortunately, if the person is super attentive, fun-loving, lays on the charm, and wants to move fast in the relationship, you need to be careful. *Anyone* can be fooled by these types, it just depends on how skilled they are at adapting. But if you have had trauma or neglect in your background, be extra careful with establishing boundaries. If you have issues with boundaries and self love, stay away from these types all together.

All three were tripping balls and only God knows what happened. Those drugs are strong and depending on how much they took they could have been talking to animals and trees.

That smirk he has on his face as he speaks is nauseating.

Don't do drugs, kids. Don't do drugs.

I really have no clue what happened to that beautiful woman. So so sad. But one thing that’s really strange to me is how Clark had enough time not to only commit suicide but he had time to write a whole suicide note! Very strange case 😢

Marianne's sister has so much hatred for Marcus, she didn't care about finding out what really happened to her, she rather take the opportunity to out Marcus in prison. She could have died from a lethal combo of substances, but seriously who kills themselves right after the police are questioning you about a death on your watch?? A guilty person usually.

I feel bad for the sister and family's loss, but I have a graduate degree and almost choked on a pancake that got lodged in my throat while stone cold sober in the middle of my office building. And I've seen just enough recreational drug use among (good/smart/kind) friends that I wouldn't rely on them to save my life in a hot tub. Being brainy doesn't translate to perfect behavior or the ability to avoid dumb accidents or dumb people. Clearly Marcus isn't a great guy, but I can't say I disagree with the jury in this. I think there were too many possibilities creating doubt around a tragic accident to convict Marcus just because he survived. You know the prosecution would have done the same thing to Clark if it was the other way around regardless of evidence.

i dunno who, if anyone, killed her but from what was provided in this story, there's more than reasonable doubt that it was marcus and not clark or a combo of drugs, alcohol, and a heart condition ... in other words they did not prove beyond a reasonable doubt that marcus did it

I don’t understand what such an intelligent woman was doing making such terrible decisions about drugs… alcohol… relationships…. It makes no sense!

39:47 - I can't stand Judges who hide behind "this court..." You mean YOU! The man was given a fair trial. He was found not guilty. But because YOU didn't agree with the jury's decision, you want to be vengeful and lock him up anyway for some meaningless drug violation.

Mary Anne seemed pretty dim considering she had a phd.

Why wasn’t Marcus charged with not calling for medical help sooner than 2 hours after her death?

"The crickets add a little crunch." me (candied nuts will do just fine)

Deputy watching Clark needs to be fired.

The fact that he said “for once in his life he was a violent guy” shows that he has some guilt for accusing his friend of the crime. He can’t bring himself to *completely* defame his character.

Drugs, sex, fantasies and a professor! Everything about this case is bizarre. Ladies, please make better choices!

The prosecution, examiners, and law enforcement made a mess of this one. Sympathies to the families and those charged.

Seriously who will take an ecstasy then jump into hot water? Consumed an MDMA itself (without any other drugs or alcohol) needs a cool even cold temperature otherwise your heart will beating too fast. As MD let me explain a little bit, MDMA dilates blood vessels combined with hot bathtube the blood vessels will dilate even more, put the body on a severe dehydration state - which results the heart will desperately pumping blood so hard as a compensation to fullfilled demands of each organs. Severe Tachycardia could end with Cardiac Arrest, esp. when the victim already has Cardiomegaly. Well, that's why the guy (Marcus) jumped out and went to the forest, instinctly he needs to cool down to maintain his heart rate. This case looks like an accident for me.

I don’t believe Clark did anything but he’s just a man with feelings and he felt guilty for being associated…if he killed her or knew what happened he would of said so in the letter.

Remember to walk away from the police when they take phone calls......

Sister 'I know my sister wasn't a careless person.' but... a highly educated adult woman is acting like a 17 year old on a fake ID, on drugs and having sex with this guy. That doesn't sound careless at all.

23:03 "I know my sister - she wasn't a careless person..." - With all due respect, allowing alcohol and drugs to enter her life at her age was kind of reckless. Drugs carry their own logic which is why this case is so messed up. "Hey you got acid? No, but I got ecstasy. Okay, close enough." This is the talk of druggies, not the most logical of people. But ultimately I think it had to do with sex and perhaps she didn't want to go along with it. She was strangled but instead of being unconscious, she was dead. Did Marcus offer this as payment for the ecstasy? It would explain Clark's sense of guilt.

If she was strangled, couldn't they look for signs on her neck? "findings on the neck were subtle. They could have come from resuscitation attempts" Umm,sure, squeezing the neck is a common technique

Why do family and close friends always make you believe that almost every victim was an angel?

Ecstasy and dehydration from alcohol is known to make you die even when no other risks are involved. And taking drugs when you have heart disease is a huge risk factor.

Idk about this one. The fact that Clark ran in the house & killed himself says alot & they barely even mentioned it. Just bc Marcus was her BF doesn’t mean he was the one who killed her (if anyone did). They really had very little/no proof of anything. I think the jury did a good job & the judge overrruled.

It's The Staircase all over again!! Drinks by a pool, a freak accident, and a husband in trouble.

That’s so sad that the family has to pay wrongful death! The man killed himself! What did his family have to do with this?

Id gotta say the old man saw a woman high as a kite and nearly nude in his hot tub all alone and went over there to see what he could get up to. He killed himself for a reason besides some drugs.

Why would any adult take LSD or any other substance ? Psychology? The blind leading the blind!

This show is such an amazing and incredible show, just enjoy how they tell all about the victims lives and who they were such a shame for all of those who have lost their lives and their families and friends who have and still deal with their loss❤

Cocaine, ecstasy , mary jane and alcohol mix can't end well.

I have no idea why the victim's self-esteem was so low that she subjected herself to this man, but also the drugs and alcohol abuse, leading to many poor decisions. And I speak as a survivor of domestic violence.

Pressure on the carotid arteries kills without getting near the hyoid bone.

”She's on the cutting edge! Of the industry!” Okay, lady.

There’s a lot of questions unanswered in this sad case of the death of Marianne Shockley, but one of the biggest ones is how the jury could only deliberate for 38 minutes. There’s no possible way they could’ve gone over all the evidence in the trial in that short amount of time.

i’m surprised a guy like that called 911 and didn’t just try to dispose of the body…which is actually what makes me think he didn’t do it

I’m glad the jury came together. So often it’s automatically pointed at the partner, but this literally has zero evidence. They weren’t even onto the whole strangling thing until others called in about it. Plus they all mentioned it was only during sex, not like when fighting ect…. I may have felt different if the part with Clark didn’t happen, but that’s so bizarre. Also him admitting why he went in the woods is kinda embarrassing but leads me to think he was being legit? Idk but it’s so so sad!! Her poor family

Marianne's sister sounds snarky. Perhaps it's pain over the death of her sister. Sad that they were all using drugs. Professor Shockley wasn't better than her boyfriend (both drug abusers). She was also post-3rd marriage. They were both prone to some very bad choices. However, I am human, and not judging her. Nobody gets it all right. I certainly don't. I hate that she died tragically. My condolences.

Most e pills during that time period were dosed extremely high. For someone who doesn't dabble in that kind of stuff often and who is also drinking and in a hot tub, that could definitely be fatal. It would also explain why she didn't want Marcus to leave because she was probably overdosing. Often times, one pill can contain enough MDMA for 3 people. Even experienced users usually break their pills in half. She probably overdosed and Clark did what he did because he knew what it looked like and he knew he wouldn't be able to handle people thinking he had something to do with it.

He's all smiling in court the whole time.

Clark took the truth to his grave. My personal opinion is he got handsey with the Prof, she refused him. He has been accused of inappropriate sexual behavior before, so… the Jury got this one right.

“Someone to have fun time with and move along “ typical reason to be killed by that “ someone “

She was a professor of poor choices

Clark confirmed that Marcus had gone into the woods when he said, “When he came out of the woods..” I actually believe the crazy story about him wanting to recreate the shaman thing. Combine that with Clark refusing orders (told four times) to stay out of the crime scene and, most of all, the suicide, I believe he (Clark) killed Marianne. Being worried because a death happened at your house and that he’d given her an Ecstasy tab just doesn’t cut it as a reason to blow one’s head off. I can picture a scenario of Marcus going in the woods, Clark gets in the hot tub with Marianne, makes a pass at her, she refuses and he flips and strangles her, also being concerned she would tell Marcus.

Let’s be clear a substance abuse issue DOES not equal you killed your girlfriend Unpopular opinion he has nothing to do with this

As far as I'm concerned charisma is like heavy perfume or cologne that someone wears when they don't take a shower. It's probably covering something else. Dr. Ramani Durvasula

I haven't gone through all the evidence, but I just don't believe there was enough to convict him.

I feel so sorry for Marianne that her life ended this way and also for Clark that left this case unexplicable.

Benjamin Franklin stated it as: "it is better 100 guilty Persons should escape than that one innocent Person should suffer".

Normal people don't choke people!!!

After everything I've seen about this case so far, I'm convinced this was an accidental death and the sister just doesn't want to accept it. Her sister wasn't the smart and sensible person she clearly wants to believe she was, otherwise she wouldn't be taking this guy on trips with her as her "assistant" (that's technically fraud, right?) she wouldn't be doing X and drinking while lounging in another man's hot tub. Clark seems as though he just had a breakdown and couldn't handle what had happened, I genuinely feel bad for him. I think he must have felt so guilty and he just made the sudden decision to end it. The cops here were and are also morons. Not only did they breach policy while at the scene, they're handling evidence in this video and contaminating it, when they don't need to. No one should be touching that note or the pad it's on. If any new piece of evidence arises and this case needs to be reopened they've just destroyed the integrity of that note and the pad for nothing more than using it as a prop in a TV show. This is a complex case which could be opened again at any time, but they don't seem to be able to engage the few brain cells they have and prevent needless contamination of evidence.

Well, some women do like this kind of excitement and that's why they get involved with dirtbags like this. She knew what she was dealing with.

Just because you don’t like a guy doesn’t make him a murderer if you can’t prove it.. I saw no arguments near where anybody should agree “beyond a reasonable doubt” that he killed her.

There’s a reason why people are ultra charismatic and can have anyone they want and it isn’t a good one. Remember, if it seems too good to be true that’s because it is!!! All the best psychopathic manipulators know this all too well……😮

Family is in denial. If Marrianne is so intelligent why was she drinking n taking drugs. Why was she dating a guy like Marcus? Why she went to hot tub when she should know its not safe in that mental condition? She was living recklessly just like Marcus was. Sister comes up with some letter which didn't even exist. The family did their level best to blame Marcus but sister own actions led her to dangerous path. N it turned out tragically.

Lol she was a beautiful person bc she cared about bugs. That’s basically what her friends said lol. Geez.

I'll tell u what, after a couple of drinks, my girlfriend & I took mdma, back I the 90's, when It was pure... we would get into my hot tub, & since heat brings on the extacy high, we couldn't even climb out of the hot tub! We actually did it twice, & both times, we had to be lifted out, due to dehydration & overheating, from the mdma/alcohol mix... just my experience on that... it made me feel like when he grabbed her out, she might have been in that state, but dropped her, which after 2 hrs of two extremely high men in a confused state, & one, who refuses to call the cops, worked on her. I feel like the older man most likely Wanted to call the cops, the other guy even says that, but says No... I think that's what he feels guilty for, in my mind...

That suicide and the timing is *VERY* suspicious. And all those women got to tell the tail.. so.. Strange case.

She had a hand in her own death. Had she been with a better group of friends she would still be alive.

There was plenty of reasonable doubt, so the jurors were correct to acquit, imo. After listening to this story, I myself had no clue how she died. The fact that Clark went and offed himself when police started asking questions was very odd & unusual and muddled the case even more. Even if he was depressed and suicidal, why do it at that exact moment? Did he do it because of a guilty conscience? Did she die as result of underlying illness, excebarated by drug use? Or did Marcus Lillard strangle her? I really could not answer after listening to this case. That letter the sister claimed to have read, pure hearsay. I am surprised she was allowed to testify about it. She seemed like she really hated the guy so who's to say she wasn't making things up? It is exactly in cases like these that a not guilty verdict is warranted, even if the defendant is not a model citizen.

Best to do drugs when one person there is sober and able to supervise in case of emergency. I’m not against drugs but I am against irresponsible use. Rest in peace bug professor 🦋

If you're so blotto that you don't know what's going on around you, be prepared to be the one to be blamed. Stay alert people ❤ I wasn't there but j suspect that they have the wrong man.

The sister lying didn’t help.

When Clark ended his life while being arrested, I just knew that was reasonable doubt. They could've pointed the finger at Clark all throughout the hearing.

I honestly don't believe Marcus killed her. I think either it was just a freak accident, due to the alcohol, drugs and heat of the hot tub.. or the older man, Clark, had something to do with it.
