Andrew Joseph Dikken, 28, previously labeled a "person of interest," is now considered a suspect in the deaths of 26-year-old Kara Monson and her boyfriend, 28-year-old Chris Panitzke of Redwood Falls.
Monson had a 5-year-old daughter.
Dikken has been at large since the shooting was discovered on Labor Day morning.
A week ago, Dikken's truck was located north of Belview, Minn., about 20 miles southeast of Granite Falls.
Authorities have warned the public not to approach Dikken if located, he’s believed to be armed and dangerous.
