Jail records show Boelter was booked into the Hennepin County Jail early Monday and included two mug shots of Boelter wearing an orange prison shirt.
Evans said the violence likely would've continued had Brooklyn Park officers not checked on Hortman's home, causing Boelter to flee.
The Hoffmans were attacked first at their home in Champlin early Saturday. A criminal complaint unsealed after Boelter's arrest indicated their adult daughter called 911 to say a masked person had come to the door and shot her parents.
After police in nearby Brooklyn Park learned that a lawmaker had been shot, they sent patrol officers to check on the Hortmans' home.
