MINNEAPOLIS—The suspect in the shooting of Minnesota lawmakers on Saturday was feeling down and unhappy with his work situation, but showed no signs that he could turn violent, his self-described best friend and part-time roommate said.

Here’s what we know about the 57-year-old charged with the murders of state representative Melissa Hortman and her husband and shootings of state senator John Hoffman and his wife.

On Saturday, Walz said Sen. John Hoffman and his wife, Yvette, were “out of surgery,” and their nephew Mat Ollig told the Star Tribune on Sunday they were “both awake now and recovering,” noting a bullet that struck Hoffman “barely missed his heart.”
