Friends and neighbors of the 57-year-old say they are struggling to understand what drove him to allegedly masquerade as a police officer and shoot two state legislators and their spouses in the predawn hours of Saturday.

MINNEAPOLIS (AP) — The man charged with killing one Minnesota lawmaker and wounding another in what prosecutors have described as a meticulously planned attack, had dozens of apparent targets, including officials in at least three other states.

Officers found notebooks referencing at least 45 state and federal elected officials in the car of suspected Minnesota shooter Vance Boelter, according to Joseph Thompson, the acting U.S. attorney for the District of Minnesota.
