Man says he had ‘psychotic break and killed’ his 80-year-old neighbor: Manhattan prosecutors

A Manhattan man has been charged with the second-degree murder of his 80-year-old neighbor, who was found stabbed to death in his apartment. Alon Riabichev, 45, allegedly told a 911 operator that he had experienced a "psychotic break" and killed Vayner with a knife before hanging up.

The arrest came after police responded to an emergency call at around 3:15 am on Monday morning. When officers arrived, they found Lev Vayner unresponsive in his apartment and covering him in blood. Riabichev was seen sitting further away from the scene inside the apartment.

According to a criminal complaint filed by prosecutors, Riabichev had initially told the 911 operator that he had lost control after a "psychotic break" and that the knife was on the table. The victim suffered multiple stab wounds, including three to his torso and neck, which ultimately led to his death.

Police revealed that both men were familiar with each other, but they were still investigating potential motives for the violent attack. Riabichev is currently being held in jail pending his next court appearance scheduled for Friday.

In an unusual lightening of violence statistics, this incident falls at a time when homicides and felony assaults in the 34th precinct, which includes Washington Heights and Inwood, have been trending downwards compared to the same period last year.
 
🤕 This is just so senseless... like what even is going on with people's minds these days? 🤯 I mean, stabbing some poor old dude to death in his own apartment... it's just not right. 😩 And the fact that the guy claimed he had a "psychotic break" but hung up on the 911 operator before they could really talk to him... who knows what was going on in his head? 🤔 It's all so tragic. 💔
 
ugh i just saw the cutest video of a puppy on instagram 🐶 and it made me think about how dogs are like the ultimate stress-relievers you know? my neighbor's dog always barks at the mailman and i'm pretty sure he's trying to protect me from getting weird bills 😂 anyway back to the news... what's up with these 911 operators they gotta deal with all this crazy stuff, poor guy had a psychotic break and still manages to sound calm on the phone 🤯
 
.. can you believe what's happening here? A guy just loses it and kills his neighbor! I mean, I get that sometimes life gets tough and people snap, but stabbing someone multiple times? That's just crazy 🤯♂️.

I'm all for mental health awareness and stuff, but this guy's excuse for the whole thing just seems so... flimsy? Like, a "psychotic break" isn't an official medical term, you know? And what's with the hang-up on the 911 call? That's when it got real 😬.

I'm trying to stay neutral here, but it's hard not to wonder what led up to this point. Were they feuding or something? Was there a history of tension between them? The police are still investigating, which is good, but it's also kinda scary that someone like this was living in the same building as his victim 🤔.

On a weird note, though, homicides and felony assaults have actually been trending downwards in this precinct... so maybe this incident just throws a wrench into those numbers? 📊
 
Ugh, another shocking case of domestic violence and the fact that the killer was able to get away with saying he had a "psychotic break" is just wild 🤯♂️. I mean, what's wrong with these 911 operators? Can't they just ask some follow-up questions or something? Like, isn't it suspicious when someone tells you their head went crazy and then hangs up on you? It's not like we're dealing with a typical mental health crisis here... anyway, glad Riabichev is in jail, but still frustrating that this kind of thing keeps happening 🤕.
 
Man, can you believe what's going on in that apartment building? I mean, 80 years old is not old, it's like, my grandma was still kicking around when she was 80 lol 😂. This guy, Alon Riabichev, he just snaps and kills his neighbor with a knife? That's some crazy stuff right there. And what's even crazier is that he calls the cops and says he had a "psychotic break"? Like, how does one of those happen in real life 🤯? I don't get it.

And the weirdest part is that the violence stats in his precinct are actually going down 📉? It's like, what's the universe trying to tell us here? Is it saying that we're getting safer or something? Idk, but I do know one thing - if you ever encounter a guy with a knife and he's having a "psychotic break", just...just stay away from him, okay? 🚫💔
 
omg what's wrong with that guy he just stabbed his neighbor to death 😱💔 i cant even believe this is real life news. i hope he gets the justice he deserves but like how could someone be so cruel and violent? 🤯 i feel bad for the victim and his family, they must be going through so much pain right now 🙏. and can we talk about how random it was that he called 911 and said he had a psychotic break lol what even is wrong with people these days?! anyway, i just hope this guy gets what's coming to him and that justice is served 💪
 
What's up with mental health calls leading to violent crimes? 🤯 We need better support systems in place, not just a quick fix like a 911 operator 💔
 
🤯 This is crazy! I mean, 80 years old man stabbed to death by his neighbor who's just 45? It's like something out of a movie. I feel so bad for Lev Vayner and his family. Who would've thought that someone you know could be capable of something like this? 🤔 I'm trying to understand what happened, but it sounds like Alon Riabichev had some kind of mental breakdown or was really unstable. 🚨 It's not right that he just hung up on the 911 operator and didn't even try to call for help or apologize afterwards. 😕 Anyway, I hope justice is served and that Alon Riabichev gets the help he needs. This whole thing is just so sad and confusing... 🤷‍♂️
 
🤕 this is so sad... how can one person go from having a neighbor to being capable of such violence? i feel for the victim's family 🤗 it's crazy that his own words against him were "i had a psychotic break" - it sounds like there were warning signs that no one picked up on
 
this is so disturbing... I mean, you just imagine someone getting stabbed like that in their own apartment and it's just not right 🤯. And what really freaks me out is that this guy claimed he had a psychotic break... like what even triggers that? anyway, at least the cops were able to catch him and now he's behind bars 💪. but still can't shake off the thought of how brutal this crime was... 😓
 
😱 what's going on with people's minds?! 🤯 45 years old, stabbing his 80-year-old neighbor... that's just crazy! 😲 I mean, I've heard of losing control in a psychotic break, but actually doing something like this is just heartbreaking. 🙏 You'd think that at some point, people would get help and get their lives together, you know? 💔 The fact that he's being held without bail is a good sign, though - maybe justice will be served and he'll face the consequences of his actions. 👮‍♂️
 
Can you even believe what just happened?! 😱 I mean, 80 years old, stabbed multiple times by his own neighbour... it's like something out of a horror movie! 🍿 And what really gets me is when the cops found the guy chillin' in the apartment, not even trying to make an excuse or anything. Just sitting there, like "oh yeah, I just killed someone and now I'm gonna hang up on you" 😒.

I don't know, man... it's just so senseless. Two lives lost over some petty beef. And what about all the other people in that building who could've been hurt?! 🤯 It's just not right. The cops are saying they're still investigating motives and all that, but I'm like "dude, at this point, it doesn't matter why he did it. What matters is that someone lost their life to a senseless act of violence". 🚔

And to make things even crazier, the precinct's homicide numbers have been going down? Like, what's up with that?! Is everyone just getting better at not stabbing each other or something? 😂 I guess you could say it's a weird silver lining, but still... my heart is heavy for Lev Vayner and his family. 💔
 
Ugh man... can't believe what's happening in our own neighborhoods 🤕. Like, I've seen some crazy stuff online, butstabbing someone in their apartment is just wild 🤯. And for it to happen between neighbors, like they were friends or something, makes me even more shook 😲. The fact that the guy claimed a "psychotic break" and hung up on 911 is already super suspicious 🚨.

I feel bad for the victim's family, of course 👪. But at the same time, I'm glad the police were able to catch this guy before he did any more damage 💯. It's always good to know that justice is being served 😌. And on a weird note, seeing the stats for 34th precinct trending down makes me think maybe we're getting safer or something 🤔? Anyway, gotta hope this one was an anomaly and not some sign of bigger issues... fingers crossed 🤞
 
😕 I cant believe what's happening in this world anymore... a 45 yr old man stabbing his neighbor to death just because he had a 'psychotic break' 🤯? That's not an excuse, that's just being lazy with your emotions 💔. As a parent, it's heartbreaking to think about how our kids are going to grow up in this world where violence can happen at any moment 👶🏻. We need to teach them empathy and understanding from a young age so they know the value of human life 🌎. And what's even more disturbing is that he claimed he had a 'psychotic break' 😂, like it was some sort of mental health issue that made him lose control 💔. Where was his support system? His therapy sessions? Something needs to change in our society... 🤷‍♀️
 
😱 can't believe what's happening in NYC right now! I mean, stabbing an 80-yr-old guy to death is just insane 🤯 and the fact that this guy claimed it was a "psychotic break" 🚨 sounds like some crazy stuff to me... how could he even justify killing someone like that? And the police found him calmly sitting in the apartment while the victim's body was still covered in blood?! 😲 what kind of mental state is that? anyway, hopefully justice will be served soon and this guy gets the help (or punishment) he needs 💔
 
🤯 can you believe that some people think they're above the law just 'cause they got a little mixed up mentally? like, Riabichev was supposed to be getting help for his alleged psych issues but instead he goes and kills this poor old man. and now he's playing it off like it was a "psychotic break" - sounds like an excuse to me. 🤷‍♂️

anyway, the thing that really got me thinking is how violent incidents are actually trending downwards in that one specific precinct... I know there's still a lot of work to be done to address systemic issues, but it's kinda weird that this one incident happens when we're supposed to be getting better. 🤔
