The suspect, whom police identified as Vance Luther Boelter, 57, fled on foot early on Saturday when officers confronted him at the Brooklyn Park home of state Representative Melissa Hortman, the top Democrat in the Minnesota House, and her husband, Mark, who were both killed.
The gunman earlier had shot and wounded another Democratic lawmaker, state Senator John Hoffman, and his wife Yvette at their home a few miles away, authorities said.
Authorities in Sibley County, about an hour by car southwest of Minneapolis, issued an alert on Sunday saying they had found the suspect’s car in Faxon Township and instructing residents to keep their doors and cars locked, the county sheriff’s office confirmed.
Officers were searching residences in the area.
The location of the car is about 6km east of Boelter’s listed home address in Green Isle, also in Sibley County, which was searched by law enforcement officers on Saturday.
The gunman had left behind a vehicle outside Hortman’s house in suburban Minneapolis that resembled a police SUV, including flashing lights, and contained a target list of other politicians and institutions, officials said.
Authorities had not publicly identified a specific motive as of Saturday evening.
The attacks started around 2am (0700 GMT) on Saturday, when authorities said the gunman shot the Hoffmans in their home in Champlin before driving several miles to Hortman’s home in Brooklyn Park.
The FBI released photos of the suspect wearing a rubber mask and a police-like uniform. (Reuters)
