A suspect is in custody after Minnesota State Rep. Melissa Hortman and her husband were fatally shot Saturday, while State Sen. John Hoffman and his wife were wounded.

Surveillance footage captured an attempted murder, according to charges unsealed Sunday: A man wearing a mask, a blue shirt and police-style tactical vest with a badge knocked on a door in Champlin and announced himself as a police officer. He then entered the house and shot Minnesota Sen. John Hoffman and his wife.

State Senator John Hoffman and his wife, Yvette, were gunned down at their home early on Saturday morning, but survived. Melissa Hortman - the top Democratic legislator in the state House - and her husband, Mark, were shot and killed. Yvette Hoffman said in a statement that she and her husband John were "devastated" by the Hortmans' deaths.

Democratic Sen. John Hoffman, his wife, and House Democratic leader Melissa Hortman were injured in what the governor describes as targeted shootings.
