US police hunt gunman after state lawmaker killed, another hurt

A manhunt was underway Saturday for a gunman who shot two Democratic state lawmakers in Minnesota, killing one and her husband and wounding the other, in what the northern US state's governor said were politically motivated attacks.

Authorities named the assailant as 57-year-old Vance Luther Boelter, who was still at large and considered "armed and dangerous." Boelter had been spotted Saturday morning in the Minneapolis area on surveillance footage obtained from a business, the official said.

The superintendent of the state Bureau of Criminal Apprehension said the authorities were still investigating the suspect's motives, and did not know if additional people were involved in the attacks. The Federal Bureau of Investigation offered a reward of up to $50,000 for information leading to the capture or conviction of Boelter.
