Vance Luther Boelter, the man accused of killing a Minnesota lawmaker and her husband and injuring another couple, planned the attacks for months and had dozens of apparent targets, prosecutors said Monday.

The man suspected of killing one Minnesota lawmaker and wounding another is now charged with murder after police arrested him Sunday near his home after a nearly two-day search.

Minnesota suspect Vance Boelter arrested after two-day manhunt, found with assault rifles and list of public officials following fatal shooting of former House Speaker Melissa Hortman.
