Right after that, this article appeared on dailyvoice.com:
A distraught man jumped to his death Friday morning from the 28th floor of a Bergen County high-rise overlooking Manhattan.
The 32-year-old jumper at Winston Towers 200 in Cliffside Park landed near the pool at 100 Winston shortly after 11 a.m., responders said.
Paramedics made the pronouncement.
The Bergen County Sheriff's Bureau of Criminal Identification was called to collect evidence. The Bergen County Prosecutor's Office was notified.
Marafioti is 33, not 32, but it's very likely that the reference above is to him.
It was assumed that Marafioti was dead 5 years ago, when he vanished without a trace for over a month. However, he reappeared, though seemed quite mentally ill.
His last tournament cash was in July 2016, just a month before that disappearance.
In the early 2010s, Marafioti made headlines as a brash young poker pro who was often controversial on social media, including some very public breakups with then-poker-pro Lauren Kling.
