Federal Grand Jury Indicts Suspect in Killing of Minnesota Lawmaker

A federal grand jury in Minnesota indicted a man on murder and stalking charges in the assassination of State Representative Melissa Hortman and the killing of her husband, Mark Hortman, officials announced on Tuesday.

The defendant, Vance Boelter, had already been charged by federal prosecutors with many of the same crimes in a criminal complaint. The indictment supersedes those charges, and is an important step in the process of bringing Mr. Boelter to trial.

If convicted of murder in federal court, Mr. Boelter could face the death penalty. Prosecutors have not said whether they would seek that punishment, though they kept that option open on Tuesday by including a notice of special findings in the indictment, said Joseph H. Thompson, the acting U.S. attorney in Minnesota. He said the final decision on whether to seek the death penalty would be made later by Attorney General Pam Bondi.

Mr. Boelter is also charged with murder in state court.

In addition to the deaths of the Hortmans, Mr. Boelter is accused of shooting and wounding State Senator John A. Hoffman and his wife, Yvette, before dawn on the same day last month. Mr. Hoffman, who was hospitalized, moved to a rehabilitation facility last week.

Federal prosecutors said Mr. Boelter was impersonating a police officer on June 14 when he went to the suburban Minneapolis homes of the two lawmakers, both Democrats, and shot them and their spouses. He visited the homes of two more Democratic lawmakers as well, federal prosecutors said, and he had a list of other Democratic politicians in his S.U.V., which resembled a police cruiser.

Mr. Boelter abandoned his vehicle and fled after encountering police officers at the Hortmans’ home, officials said. A two-day manhunt that was described as the largest in Minnesota’s history led to his arrest in a rural area near his home in Sibley County.

The attacks in Minnesota came at a time of rising political violence in the United States. Officials in some states have promised to take a closer look at the safety of state legislators, who generally have no special security protection and whose home addresses are often posted on government websites and official documents.

Ms. Hortman, a former speaker of the Minnesota House of Representatives, was remembered by colleagues as a thoughtful lawmaker who was willing to work across party lines. When her party had full control of state government in 2023 and 2024, she helped pass bills that expanded abortion rights, legalized recreational marijuana and required employers to provide medical and family leave.

Mr. Hortman, who worked for an electrical manufacturing company, was recalled by friends as an enthusiastic and supportive political spouse with a sense of humor and an interest in sports.

Former President Joseph R. Biden Jr., former Vice President Kamala Harris and Gov. Tim Walz of Minnesota were among the officials who attended the Hortmans’ funeral in June.
