A naked man who went on a stabbing spree at his apartment building, killing two people and injuring three others, was charged with murder Wednesday, police said.
Christian Falero was arrested after he randomly knocked on several tenants' doors in the seven-story Washington Heights building in Manhattan on Tuesday afternoon and stabbed those who answered with a 10-inch kitchen knife, police said.
Police charged the 23-year-old Falero with second-degree murder and robbery. Additional charges were expected after the death of a second victim, 65-year-old Yigao Chen, on Wednesday.
A second-floor tenant, Ignacio Reyes-Collazo, 81, was killed during the attacks. His 75-year-old wife, Margarita Collazo, underwent surgery and was recovering, the couple's son, Cesar Castro, told The Associated Press.
An 85-year-old woman was also stabbed, and a 22-year-old home health aide was punched. They were hospitalized in stable condition.
Residents said afterward that the suspect was seen running down the street yelling that it was the end of the world. Falero had self-inflicted stab wounds when he was arrested, and he was taken for a psychiatric evaluation, police said.
No attorney information was immediately available for Falero.
Castro said his father was a Korean War veteran and once worked in security at Columbia University.
"Everybody around the block loved him," Castro told the AP. No attorney information was immediately available for Falero.
The suspect's fifth-floor neighbor, Ramon Acosta, said Falero always seemed likable. Acosta came home from work Tuesday to find police outside the building and Falero's mother in tears.
Acosta said he had known Falero for 10 years and never had a problem with him.
"I guess he just flipped," he said.
