A man wanted in a triple shooting that left two people dead in Staten Island was wounded by police as they tried to arrest him in Pennsylvania, officials said.

State Police and the U.S. Marshal's Service said 49-year-old Anthony Morales was shot when he reached for his waistband as officers ordered him to get out of his vehicle Monday night in Hamburg. A loaded handgun was found on him.

Police said Morales was in stable condition at a hospital.

Morales was wanted in a March 24 shooting that killed 47-year-old Idelle Rivera and her 21-year-old son, Anthony, in the Mariners Harbor section of Staten Island.

Investigators said a 22-year-old man was also shot, but survived.
