MINNEAPOLIS — The man accused of killing a Minnesota lawmaker and wounding another went to the homes of two other legislators on the night of the shootings, intending to inflict more carnage against those on his hitlist, a federal prosecutor said Monday.
But one of the other lawmakers was on vacation and the suspect left the other house after police arrived early Saturday, acting U.S. Attorney Joseph Thompson said at a press conference.
The suspect, Vance Boelter, meticulously planned out the attacks, carrying out surveillance missions, taking notes on the homes and people he targeted and disguising himself as a police officer on the night of the attacks, Thompson said.
''It is no exaggeration to say that his crimes are the stuff of nightmare,'' he said.
Boelter surrendered to police Sunday after they found him in the woods near his home following a massive manhunt over nearly two days that began near Minneapolis. He is accused of posing as an officer and fatally shooting former Democratic House Speaker Melissa Hortman and her husband, Mark, in their home early Saturday in the northern Minneapolis suburbs.
Authorities say he also shot Sen. John Hoffman, a Democrat, and his wife, Yvette, who lived just a few miles away.
Federal prosecutors announced Monday that they have charged Boelter, 57, with federal murder, stalking offenses. He already faces state charges, including murder and attempted murder.
Boeltner had many notebooks full of plans and made efforts to find the addresses of his victims and their family members, Thompson said. But authorities have not found any writings that would ''clearly identify what motivated him,'' he said. Though the targets were Democrats and elected officials, Thompson said it was too soon to speculate on any sort of political ideology that could explain his motives.
