Third victim of knife-wielding maniac who left a bloody trail in Manhattan on a stabbing spree in broad daylight Police and sources said on Monday that the wild man died from injuries he sustained after confessing to random killings and being slapped with murder charges.

The 36-year-old woman, who was the third and final alleged victim of 51-year-old Ramon Rivera, died from her injuries at the hospital Monday evening, police said.

Rivera, a homeless man have an extensive criminal record He allegedly admitted to the unprovoked stabbings, which began in the morning and occurred in a part of the county from Chelsea to the East River, that he was experiencing mental health issues, sources told The Post.

A 36-year-old male construction worker waiting to be picked up from work and a 67-year-old man fishing on the East River were also killed in separate stabbings by the same suspect in Manhattan, police said.

Rivera, who was released from Rikers a month ago and lives at the Bellevue Men’s Shelter, has been charged with three counts of murder, police announced shortly after 9 p.m.

He walked with his head down and did not answer reporters’ questions as he was led out of Manhattan’s 10th District Monday night wearing a white jumpsuit, handcuffs and ankle shackles. The accused killer stared icily at the crowd of reporters and onlookers as he sat in the back of an unmarked squad car.

Police officials said the killings were random and unprovoked.

“As of now, these attacks appear to be unprovoked; the man walked up to them and began attacking them with knives,” NYPD Chief of Detectives Joe Kenny said at a morning press conference.

The grisly, bloody crime spree began around 8:20 a.m. when construction worker Angel Lata Landi of Peekskill walked up to him, stuck a knife in his stomach in front of 444 W. 19th St. in Chelsea, and fled. in question.

About two hours later, Rivera arrived at 500 E. 30th St., where he allegedly attacked the fisherman, according to cops. It resurfaced near FDR Drive at.

He fled north toward East 42nd Street and First Avenue and allegedly stabbed the 36-year-old woman about a half hour later in the shadow of the United Nations building as terrified bystanders rushed to help.

Landi and the 67-year-old victim were taken to Bellevue Hospital, where they were both pronounced dead. The seriously injured woman was taken to Weill Cornell Medical Center, where she was later pronounced dead.

The identities of the other two victims were withheld by police pending notification of the family.

Several Good Samaritans helped police capture the violent lunatic. A British tourist and UN diplomatic security worker helped track down the suspect, while a taxi driver followed and replaced a nearby NYPD officer, Robert Garvey, who eventually handcuffed Rivera and restrained him from further senseless stabbings.

“If Officer Garvey had not been there, these random acts of violence, this individual would likely have continued these random acts of violence,” Mayor Eric Adams said at the press conference. “So he saved the lives of his fellow New Yorkers.”

Police recovered two bloody kitchen knives believed to have been used by Rivera.

The alleged killer was arrested last year for burglary, assault and grand larceny and suffered two mental health crises for which police responded, sources said.

Adams said it’s unclear why Rivera returned to the streets.

“There are some real questions we need to look at as to why he was on the street, and there are some serious mental health issues that need to be examined, and that’s what we’re trying to determine in the investigation,” the mayor said. .
