Juan Alonso, 50, has been charged with murder, manslaughter, and criminal possession of a weapon after police were called to an apartment in the Bronx Sunday evening.

The machete wielding man is accused of fatally hacking up a man he met on Grindr. The victim’s name is still unknown as police were still trying to identify him. What is known, though, is that Alonso’s roommate walked in on the bloody aftermath of the slaughter, police sources said Monday.

The roommate, who had been away, returned home to the apartment he shares with the suspect on E. 206th St. near Perry Ave. in Norwood about 7:10 p.m Sunday. He found Alonso, machete in hand, standing over the dead victim, sources said.

The victim was lying face down with stab wounds to his head and back, authorities said.

“He was like so cut up,” building super John Gonzalez, 33, told the Daily News, adding the victim was “on the floor in pieces.”

“I asked him what happened when they were putting him in the squad car,” he said “He said he was trying to defend himself. He said he was in the bed sleeping — and when he woke up, there was someone was on top of him trying to rape him…He was out of it.”

“He was a good guy,” said Gonzalez, who has worked at the building for seven years. “I always talked to him. He always was calm. He didn’t look like the type of guy who would do something like that.”

“He must have been pushed to the edge,” said Cathy Lopez, 42, a long-time friend of Alonso. “Manny is not a violent guy.”

She added, “Manny was a cook. He made Mexican food in his apartment and sold it on the street.”

Alonso told her he had been abused by past roommates, Lopez said. “I don’t know how he met them,” she said. “Manny took roommates to pay the rent. And they turned on him…. Someone can only take so much.”

Alonso was wrapped in a blood-soaked bed sheet when police escorted him out of the apartment complex.

Since his arrest, his arraignment in Bronx criminal court was delayed because he was hospitalized for a psychiatric evaluation, court sources said.
