A naked man who went on a stabbing spree at his Manhattan apartment building, killing an elderly man and injuring four others, was charged with murder on Wednesday, police said.
Christian Falero, 23, was arrested after he randomly knocked on several tenants' doors of the seven-story Washington Heights building and then stabbed the people who answered with a 10-inch kitchen knife, police said.
Police charged him with second-degree murder and robbery.
A second-floor tenant, Ignacio Reyes-Collazo, 81, was killed during the random attacks that unfolded around 4 p.m. Tuesday. Three women, ages 60 to 85, were stabbed and a 22-year-old home attendant was punched, police said. They were all taken to area hospitals; one of the women was in critical condition, the others were stable.
