NYC Teen Killed His Father, Victim's Girlfriend and Their 5-Year-Old Son After He Believed Couple Was 'Going to Hurt Him': Cops

A Bronx teen was charged with murder after his father, his father’s girlfriend and their 5-year-old son were found stabbed to death, according to authorities.

Police responded to a 911 call at a building in Mott Haven and found 38-year-old Jonathan Rivera dead in the first-floor hallway, the New York Post reported. Rivera’s girlfriend, 33-year-old Hanoi Peralta, and the couple’s son, 5-year-old Kayden Rivera, were also found murdered inside the apartment.

Police said the attack on Kayden left him essentially disemboweled.

The suspect, Rivera’s 19-year-old son Jayden Rivera, had been babysitting his half-brother on Nov. 25 while his dad and Hanoi went on a date — just hours before police believe the killings occurred, The Post reported.

Officials said Jayden left the apartment after the stabbings, but then returned and allegedly pounded the bodies with a kitchen pot.

Jayden, still covered in blood, reportedly returned home to the Bronx apartment he shared with his mother, police said. According to officials, he allegedly told his mother he was “hearing voices” before the triple slaying.

NYPD Chief of Detectives Joseph Kenny told The Post that the suspect "thought that Mr. Rivera and Ms. Peralta were going to hurt him.”

Jayden, a student at SUNY Oswego, was transported to a psychiatric ward at Westchester County Medical Center, where he allegedly confessed to hospital staff and county cops, The Post reported.

Jayden was charged with murder, manslaughter, and criminal possession of a weapon, authorities said.

“I feel this is not supposed to happen," Jonathan’s father, Miguel, told The Post. "The day they told me I was thinking this was like a movie. But, no. Now it’s real.”
