A federal grand jury indicted Vance Boelter on six charges in the shootings that killed state Rep. Melissa Hortman and her husband, Mark, and injured state Sen. John Hoffman and his wife, Yvette.

A Minnesota man plans to plead not guilty to charges he killed the top Democratic leader in the state House and her husband​ after wounding another lawmaker and his wife​, his attorney said.

Acting U.S. Attorney Joseph H. Thompson said the indictment includes a "notice of special findings," which he says is the first step in seeking the death penalty.
