NEW YORK (AP) - Authorities say the person in custody in an attack in New York City that left four homeless men dead also appears to be homeless.
  
Deputy Chief Inspector Michael Baldassano said at a news conference Saturday that authorities continue to check the Chinatown neighborhood for any additional victims.
  
Baldassano said five sleeping homeless men were attacked early Saturday morning in different locations throughout the neighborhood. The attacker used a metal pipe on the victims. Four were found dead and one remains in critical condition.
  
He said the attack appears to be random.
  
Police responded to a 911 call just before 2 a.m. when one assault was in progress.
  
Police say the 24-year-old in custody has yet to be charged.
