BELLE PLAINE, Minn. >> The man suspected of shooting two Minnesota lawmakers, killing one, remains on the loose more than 36 hours after the shootings took place.

Authorities said in a news conference Sunday evening that Vance Boelter was not in custody. They believe he is still alive.

Authorities searched a car Sunday they believed Boelter was using in the suburbs outside of Minneapolis the day before, when the shootings took place.

Drew Evans, superintendent of the Bureau of Criminal Apprehension, said they found evidence in the car relevant to the invest- igation.

He did not provide more details.

Evans said authorities interviewed Boelter’s wife and other family members in connection with Saturday’s shootings. He says they were cooperative and are not in custody.

Former House Speaker Melissa Hortman and her husband, Mark, were killed in their Brooklyn Park home early Saturday. Sen. John Hoffman and his wife, Yvette, were injured at their Champlin home, about 9 miles away.Authorities named Boelter, 57, as a suspect, saying he wore a mask as he posed as a police officer, even allegedly altering a vehicle to make it look like a police car. Authorities searched the vehicle on a rural road as a state on edge struggled to make sense of the brazen political violence.

More than 36 hours after authorities first confronted him outside Hortman’s home, Boelter was still on the loose after fleeing on foot. The FBI issued a reward of up to $50,000 for information leading to his arrest and conviction. They circulated a photo taken Saturday of Boelter wearing a tan cowboy hat and asked the public to report sightings.

Investigators found a cowboy hat near the vehicle and determined it belongs to Boelter, Evans said. Law enforcement officers were searching the area, including nearby homes.

The search was happening in rural Sibley County, roughly 50 miles (80 kilometers) southwest of Minneapolis, where Boelter had a home with his wife and five children. Residents in the area received an emergency alert about the located vehicle that warned them to lock their doors and cars.

A crowd of officers were seen congregated on a dirt road near the abandoned dark sedan. Some officers broke off and walked into a wooded area off the road. The car was later towed away. “We believe he’s somewhere in the vicinity and that they are going to find him,” U.S. Sen. Amy Klobuchar of Minnesota said Sunday on NBC’s “Meet the Press.” “But right now, everyone’s on edge here, because we know that this man will kill at a second.”

The shootings come as political leaders nationwide have been attacked, harassed and intimidated amid deep political divisions. Lawmakers said they were disturbed by the attacks as Twin Cities residents mourned.

Brightly colored flowers and small American flags were placed Sunday on the gray marbled stone of the Minnesota State Capitol along with a photo of the Hortmans. People scrawled messages on small notes including, “You were our leader through the hardest of times. Rest in Power.”

Pam Stein came with flowers and kneeled by the memorial. An emotional Stein called Hortman an “absolute powerhouse” and “the real unsung hero of Minnesota government.”

“She had a way of bringing people to the table and getting things done like no one else could do,” said Stein, a retired lawyer. The Hoffmans were recovering from surgery, according to their nephew, Mat Ollig.

No details on motive.

Authorities have not yet given details on a motive.

A list of about 70 names was found in writings recovered from the fake police vehicle that was left at the crime scene, the officials said. The writings and list of names included prominent state and federal lawmakers and community leaders, along with abortion rights advocates and information about healthcare facilities, according to the officials.

A Minnesota official told the AP that lawmakers who had been outspoken in favor of abortion rights were on the list. The official spoke on the condition of anonymity because the investigation was ongoing.

The attacks prompted warnings to other state elected officials and the cancellation of planned “No Kings” demonstrations against President Donald Trump, though some went ahead anyway, including one that drew tens of thousands to the State Capitol in St. Paul.
