(WHEC) Authorities say a gunman was “on a mission” to target and kill his family members in New York.

Police believe 39-year-old Terrell Blake shot his ex-wife and her boyfriend at home in Rochester Wednesday. 

Investigators say he then drove a U-Haul to another home and shot his 20-year-old son. The woman died in the shooting, but the two men are expected to survive. 

Blake then led police on a chase through the city in that U-Haul. He later died in a shootout with police.
