State Rep. Melissa Hortman and her husband, Mark, were killed in their home.
GREEN ISLE, Minn. -- The massive search for the man suspected of the fatal shootings of Minnesota lawmakers concluded on Sunday evening when he was arrested by police, multiple sources confirmed to ABC News.
Vance Boelter, 57, was arrested near his farm in Green Isle, Minnesota. He was spotted on a trail via camera earlier Sunday and then taken into custody, sources said.
He is accused of the fatal shootings of Minnesota state Rep. Melissa Hortman and her husband, and a separate shooting attack on another state lawmaker and his spouse.
The twin attacks in Champlin and Brooklyn Park, Minnesota, on Saturday led to the discovery in the suspect's vehicle of an alleged target list of dozens of Minnesota Democrats, including Gov. Tim Walz, U.S. Rep. Ilhan Omar, U.S. Sen. Tina Smith and state Attorney General Keith Ellison, according to law enforcement sources.
During a press conference Sunday evening, police said a hat believed to be associated with the suspect was found near his alleged vehicle. There were several items of evidence relevant to the ongoing investigation found in the vehicle outside of the alleged target list, police added, but did not disclose what else was discovered.
The discovery of the hat is what led authorities to believe Boelter was in the area.
Police said that Boelter had been in contact with individuals, but were trying to determine if he was receiving any assistance while on the run from law enforcement. "All options are on the table," said Drew Evans, the superintendent of the Bureau of Criminal Apprehension in the Minnesota Department of Public Safety said earlier Sunday.
The FBI was offering a $50,000 reward for information leading to Boelter's arrest.
There was a nationwide warrant for Boelter's arrest on a state level and a federal warrant for unlawful flight to avoid prosecution, police said Sunday.
