U.S. Attorney Joe Thompson announced that the suspect in the murder and attempted murder of Minnesota state lawmakers was charged with six federal crimes in addition to state charges.

Vance Boelter was arrested near his home in Green Isle, Minnesota, on Sunday night, two days after the deaths of Democratic Minnesota House Speaker Melissa Hortman and her husband, and the attempted murder of Democratic state Sen. John Hoffman and his wife. Thompson confirmed that his office filed its complaint against Boelter for his alleged “horrific attack” on the Minnesota lawmakers.
