State Rep. Melissa Hortman and State Sen. John Hoffman, who were targeted by a shooter on Saturday, were longtime members of Minnesota's state legislature.

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.

Early Saturday morning, when a man dressed like a police officer knocked at the home of a Minnesota state legislator, marked the start of nearly 40 hours of violence and fear that swept through towns in an arc around Minneapolis.

A manhunt is underway for the gunman who was impersonating a police officer and had a list of possible targets, officials said.

Governor Tim Walz of Minnesota commended the family of John A. Hoffman, saying their actions during a gunman’s attack on Saturday saved “countless lives.”

Minnesota State Rep. Melissa Hortman, State Sen. John Hoffman and their spouses were all shot early Saturday in targeted attacks.

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.
