Vance Boelter is accused of posing as a police 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, at their home in a nearby neighborhood.

A federal prosecutor said Vance Boelter went to the homes of four politicians in a deadly rampage in Minnesota on Saturday.

The suspect built a scattered career ranging from food to retailing to private security to pastoring, public records and his online postings show.
