Minnesota authorities are looking for a man they believe has information about the killing of a woman in Granite Falls. The Bureau of Criminal Apprehension says that Granite Falls Police responded to a 911 call at about 3:30am Monday. They found a 28-year-old woman dead of a gunshot wound, and a critically injured 28-year-old male. Investigators say that 28-year-old Andrew Jospeh Dikken of Granite Falls is a person of interest in the killing. Police believe he is driving a 1996 Brown GMC Sierra “Club Cab” pickup truck with a topper with Minnesota license plate 032-GGL. Dikken may be armed and dangerous, and anyone who thinks they see him is asked to call 911. The shooting victims have not been identified.
