Vance Boelter, the man accused of killing a Minnesota state legislator, her husband, and wounding two others, was slapped with upgraded state charges on Thursday.

The man accused of killing Minnesota lawmaker Melissa Hortman and her husband, while wounding two others in June during an alleged coordinated attack has been indicted by a grand jury on eight total charges.

Vance Boelter, 58, of Green Isle, Minnesota, was indicted July 15 on six counts of murder, stalking and firearms violations. The murder charges could carry the federal death penalty, though prosecutors say that decision is several months away.
