NEW YORK – Ramon Rivera, 51, the the alleged New York serial killer facing murder charges, appeared in court on Tuesday with the families of his victims in attendance as concerns grow over his extensive criminal record.

FOX 5 NYLisa Evers spoke with the family of Angel Landi, 36, a father and construction worker from the Bronx who was killed in the stabbing.

In an interview, Landi’s sister Berta described him as a “hardworking” single father from Ecuador who took in his nephew after his sister’s death and raised him as his own.

“I want justice for my brother,” said Berta. – He died at work.

His 16-year-old nephew, who called Landi “daddy” and was in his custody, also spoke to FOX 5 NY. “I hope he rots in jail and never gets out,” the teenager said of the alleged killer.

Rivera, who is believed to be homeless, has a criminal record in three states and was arrested for grand theft just last month. Despite his violent past, Rivera had taken to the streets, highlighting systemic problems in preventing such tragedies.

“I don’t understand why, if he had felonies on him and more than eight charges, why they would still let him out,” said Landi’s son.

He also criticized NYC Mayor Eric Adams’ response to the arrest: “I understand the point of view he’s coming from, but if you’re running the city, then you should be responsible for it. You’re the one who said you were going to protect these streets and help other people and so far, I’ve seen nothing done.”

What happened in the stabbing in New York?

Surveillance footage shows Rivera putting on gloves and pulling a knife from his backpack shortly before the attacks. Police say the gloves seen in the footage match those found at one of the crime scenes, along with two knives.

The violence began around 8:30 a.m. near West 19th Street and 8th Avenue, where Rivera allegedly stabbed a construction worker, Angel Lata Landi, 36, in the abdomen. He was rushed to Bellevue Hospital but did not survive.

Nearly two hours later, police say Rivera struck again on East 30th Street near the FDR Drive, attacking a 68-year-old man who was fishing along the East River. The man also succumbed to his injuries.

Just 30 minutes later, Rivera allegedly stabbed a 36-year-old woman, Augustin Wilma, multiple times at 42nd Street and First Avenue. She was pronounced dead at Cornell Medical Center.
