The Deadly Obsession of Riley Gaul 

I’m really glad those 2 young men, Noah and Alex, called the police on their friend, helped the police recover the murder weapon with fingerprints still on it, recorded their friend for evidence, and testified against him. They put Justice for Emma above their friendship, and never forgot who the true victim really was all along. Their parents raised them right, they should be proud of them😊

Riley Gaul: "I would never hurt THAT girl" Chris Watts: "I would never hurt THOSE kids"

if my girlfriend broke up with me i would simply move on and not harass and murder her but hey thats just me

His "Plan B" to win her back was a bouquet of flowers, a love letter, and a Nordstrom's gift card. He chose unwisely.

Reily: I love her so much. Detective: who? Reily: the dead girl Detective: oh yeah, I can tell.

"Yeah, I psychologically and emotionally abused her, but I never meant to actually cause physical harm." Riiight. That's what all abusers say.

Imagine throwing your entire life away over a high school relationship lol

The friends who lured him into the trap are the real MVP's

Kudos to his friends for doing the right thing.

Killed herself? By shooting herself through the walls of her house? That's a hard one to believe

"They like took me to their van or whatever" ....sounds legit

"I loved Emma" at the same "I caused her emotional and psychological pain and wanted to manipulate her into confiding in me"... The word "love" just lost all meaning...

Teenage love, so dramatic, so painful and yet a few years later you wouldn't recognise them if you saw them in the street. I have tried to always make sure our daughter is aware that it is not forever and no one is worth ruining your life over. Eat a tub of ice cream and forget them.

Riley:The girl uh she text me Detective: what girl? Riley: the one that passed away So many things stuck out when he spoke of her like that.

He didn’t love her, he loved having her. This is such an important differentiation.

“I luv ye bro” “we got ur back bro” performing under pressure. I love these kids.

Guy: commits murder Guy's mom everytime: "my baby's innocent!!!!!"

"I didn't kill her but can you guys help me hide this gun?"

Shoutout to Noah and Alex for having the moral clarity to turn him in at such a young age.

I broke up with my boyfriend and shortly after, met the man that I would marry. My ( ex ) boyfriend said he wished me well. We played tennis as we always had, and afterward, he lunged at me and was strangling me. I played dead. He picked me up and headed out to the balcony ( 23rd floor ). as he got to the door I stiffened up so he couldn’t go through. He looked like he was snapping out of a trance and said: “ I don’t know what got into me” I said: “ well, no harm done, let’s have a glass of wine....” ( I really said that ). He said “ I have to go to the bathroom first...”. When the bathroom door closed, I ran like hell up and down the hallway knocking on doors and finally a young guy ( with a wife and children! ) let me in to call the police. When they got to his apartment he had done a “ legger” and I had to have protection to and from work etc. within a few weeks I left the island ( Oahu ) , married my husband, and we moved to London. That was 40 years ago ( July 18 ) and I’m breaking into a sweat writing about it still. I was very lucky ! ( as he was choking me he said “ if I can’t have you... yada yada yada”..... even at the time I thought “ how cliche!”... )

Spoiled brat that was handed everything. The one thing he couldn’t have, he killed.

He didn't kill her because of love or whatever. He doesn't know what love is. He killed her because she hurt his ego.

Ahhhh such a smart move to distance yourself by saying "that girl". Yep. Nobody's going to know, dude. Nobody's going to know.

This shook our community. He recently tried to file for a new trial. He was denied :)

Basically his mindset is if he can’t have her, then no one can have her

I hate this one. She seems like such a sweet girl and good for the earth. Destroyed by this weirdo

Everytime one of my gf's get killed, it's standard practice for me to get rid of all my guns in the nearest river. Sounds pretty innocent to me.

If it weren't for Noah and Alex this may not have been solved. Thank you and God bless. We need a LOT more people like these two young men in the world

Riley: "How do I make Emma love me again??" Friend: "Have you tried flowers and professing your undying love?" *Proceeds to kidnap himself and throw himself in a ditch*

Something about him continually referring to her as "that girl" while being investigated is so off-putting to me.

His friends were instrumental in his arrest, well played lads.

It’s scary how accurately the “DENNIS” method fits this guy

Man the defense attorney sounded like he didn’t believe his own argument

"The girl" which girl? "The girl that passed away" ummm u can't even say her name? The girl u were so in love with?? Huge red flag right there⚠️⚠️⚠️

"she killed herself" how does someone shoot themselves through a wall bruh

I hope the parents and friends of Alex and Noah are SO proud! Thats an absolutely terrifying situation and they were strong enough to keep calm, and make sure that an innocent girl could get justice after death.

I don't know why but when he started referring to her as the girl, it really shocked me, like you could clearly see how after he had done the deed, he had completely disconnected her from his life.

Thank you to all my ex boyfriends that just treated me like shit and then disappeared. 👍

Shot in the head through the wall? That's actually terrifying...

Can you imagine the deep hurt her father must feel? One that he didn’t try to wake her. Two that she didn’t call him when there was a weird guy outside his house. That would devastate me

Never date a person who is cheating on their partner with you. Speaking from personal experience it’s awful and they will not change.

He was a wide receiver in high school now he a wide receiver in prison. Never give up on your dreams ❤

I hate it when I'm out for a stroll at night and I get randomly kidnapped for no apparent reason and rudely thrown into a ditch.😢

Good on those two boys for not only going directly to cops, but literally putting themselves in danger to make sure he was caught. I respect them greatly.

Good thing he "trusted" his friends that much.

13:20 "I wouldn't hurt that girl" Then why can't you even say her name, you psycho. And Chris Watts did this too. He refered to his daughters as "those kids."

I live in Knoxville. There's a dog park named for Emma Walker that I go to frequently. Had no idea how she died, and I happened to click on this video. Very sad.

This is why it angers me when "I hate you but I love you" relationships are glamorized in media. It's not cute, it's not their "special way" of showing they "love" you, your love will NOT change them into becoming a better person, instead it usually always ends in toxicity and break up violence. Sometimes, as portrayed in this case, it ends in the most drastic and heartbreaking way.

“The girl” “The one that passed away” WTF🤨😳🤭👎😑 Crazy how he couldn’t refer to her by her own name.... 🤷🏻‍♂️

You heard him. He’s only sad because he got caught.

every time I hear the moms call it makes me want to cry, the pain in her voice is real.

Lawyer: “Now I suspect, that makes very little sense...” Everyone else: ......you don’t say.

Well if I ever go through a break up I will be rearranging my room.

When he referred to her as "that girl" it was chilling. No doubt the detective was immediately convinced that he was involved.

Well Riley certainly didn't do a good job of proving the "dumb jock" stereotype wrong. "They like, threw me into their van or whatever" yeah sounds like you're really traumatized.

Today is Emma's 21st birthday, and even though she isn't here to celebrate it, she deserves to know how much we cared about her. RIP Emma Jane Walker😭💖A beautiful sweet loving angel gone too soon.

I have NEVER seen a more accurate and REAL interpretation of the D.E.N.N.I.S system. Kudos for pointing this out, mai gai. ❤

His friends, Noah & Alex, deserve some credit for turning him in.

At least his friends who went to the police had some class. I appreciated that.

Finally, a case where the friends DON'T help them cover it up.

I appreciate the zoom in on "Cat survives fire" because that was the only thing I was looking at

"They just... took me to their van, or whatever..." Pretty sure if you're trying to convince the cops you were kidnapped, you wouldn't speak of it that way..

It took me years to get rid of my obsessive high school boyfriend. He was older than me and popular. He would show up at my job, practice, talk to my friends to get information about me, he’d show up at my house. I had no one to help because I was too young and naive to articulate my feelings to my parents they would allow him to spend time at our house even after the break up. A lot can go on within a teenage relationship that others don’t know about. Boys like Riley are good at showing people who they want to be seen as.

"I hope to god i'm not a suspect in this case." Wow amazing. This shite isn't the brightest crayon in the box. 🙄

His words at the end where he says that he only mistreated her psychologically, but never intended to kill her. Is that supposed to make him look better?

Me: *DEEP INHALE* Mike: Heyyy you! Me: god damn that’s good.

The police: "Sir, we'd like to ask you a few questions." Riley: "I didn't kill her!"

if my ex boyfriend referred to me as 'the girl' after murdering me id punch him in the face as a spirit lmao

I'm still trying to figure out how a guy was so reckless with everything else but also managed a perfect head shot through a wall

I do not miss high school at all. A lot of football player’s were pos’s.

why did he ask for help about throwing a gun in a river...

Even at court, can't stop talking about his own damn self. These people are all the damn same. Shameful.

Why involve his friends to get rid of the gun? Total stupidity

To the two friends that turned him in…you both are the real hero’s here! And Riley I hope when he closes his eyes he’s haunted by what the hell he did everyday

He's cold hearted human being.. That poor girl deserve so much more. 😢

12:11 "The Dennis System" That is actually pretty insane cause this kid did that exactly. And I always took Mike for a guy that would watch it's always sunny

"The girl." *We got "The boy." guys. Case closed and shut.*

I’m sorry but when you compared the situation to the DENNIS system I couldn’t stop laughing

He shot INTO her house! He shot EXACTLY into her bedroom and into her BED! Exactly where she was sleeping! If he was trying to scare her and not cause harm, he could have shot into the air. For sure this was no accident and no way was this a way to scare Emma. You can't fool anyone with that excuse.

she wasn’t the woman of his dreams , she was still a kid.

Good Riddance..By sending him to prison there’s no telling how many other lives they’re saving..

Noah and Alex…outstanding job. Quality young men who did what was right. They didn’t let the pressure of friendship keep them silent. This scumbag deserves everything he gets.

"The girl, the one that passed away". Guilty!!!

Give it up to his “friends” for turning him in. Well done Gentlemen

I wish she’d gone to her adult dad when she was scared instead of her ex teen boyfriend

That defense attorney was grasping at straws. I mean, the next step would be to claim his evil twin did it.

"The girl", he was trying to distance himself form the crime and how obsessed he really was

"My son is innocent!" Says every mother ever.

Holy shit he full on used "the D.E.N.N.I.S. System" on her. 😳

Noah and Alex…….. I have probably seen this video about 10 times now, but if by chance you ever see this I want you to know how absolutely amazing it was that you did the right thing! It’s hard to look past friendship to do what’s right and you did! Respect

If I sent my girlfriend a text like he sent Emma, I would have to leave the country and go hide somewhere godawful where she wouldn’t follow me...

I’m from Knoxville and went to High School with them both. I grew up in the same age group as Riley, I was never friends with him or any of his associates but I did share classes with him growing up through middle and High school. He seemed like your typical football player. He goofed around a lot. This just goes to show you that you never know what people are capable of. People can seem so normal, yet be so sick in the mind. Emma was a sweet girl... He deserves life for what he did.

Cat survives house fire :)

I think when parent (s) put their children on such a pedestal; those type of kids can’t handle the smallest rejection!!! Teach your children ( confidence) ! But also , teach them rejection is a part of life and it’s ok !!

It's tragic Emma died, and the only good thing to even remotely come out if it was that her killer was brought to justice because odds are he would have done this kind of shit to a different woman if he was still outside among the public.

You always hear about the crazy ex girlfriend, that's because when it's the crazy ex boyfriend, there are no survivors.

I had an extremely hard break up with my ex fiance and still care about her as a person but I could never imagine hurting her let alone killing her. That is just plain psycho behavior.

He'll be like 75 years old when hes eligible for parole. Hopefully it gets denied then

Imagine taking No so hard you have to take a life. This guy is sick. Grown baby

He's been in her bedroom. He knew exactly where her bed was, and where her head would be. He aimed, and shot twice. That's murder.
