THE BRONX (PIX11) — Two people were fatally stabbed and a third person was slashed during an argument Friday night inside a Bronx apartment building, police said on Saturday.

A 45-year-old man and two women were standing in a stairwell area inside 3145 Rochambeau Ave. around 10:20 p.m. when they met the suspect, police said. The suspect groped one of the victims, a 29-year-old woman, which led to an argument between the victims and the suspect, according to police.

Eventually, the victims followed the suspect to an eighth-floor apartment where police said the assailant pulled out a sharp object, stabbed the 29-year-old woman in the chest, and slashed the 33-year-old woman in the hand. Both women then fled the apartment, police said.

The 45-year-old man continued to spar the attacker and he was stabbed several times in the chest, police said. First responders pronounced the man dead at the scene. Both women were taken to a hospital, where the 29-year-old later died.

The two victims who died were boyfriend and girlfriend, according to police sources.

The suspect fled the scene on a motorcycle and was still on the loose, as of Saturday. The man lives in the apartment where the stabbings happened, police sources said.

Rich Mendoza, a tenant at the Bronx building, was shaken after hearing the details of the incident.

“It’s nerve-wracking, but what can you do about it? With the pandemic people are going crazy. People are going crazy,” he said.

Police said it was unclear why the victims were at the apartment building. None of them lived there.
