Killings of homeless men shake New York's Chinatown

The deadly bludgeoning of four homeless men while they slept in Manhattan's Chinatown has startled the city. A fifth victim was left in a critical condition.

Randy Santos, 24, who also is homeless, allegedly confessed to the crimes in which he used a 3-foot (90-centimeter) length of construction metal, Manhattan Assistant District Attorney Alfred Peterson said, according to The New York Post.

"While he was in the 5th Precinct, he was shown video of the attacks and he admitted that he was the person in the video," Peterson said.
