They recounted a horrifying tale of an unknown man breaking into their home and viciously attacking them with a knife. Inside the apartment, the lifeless body of Robert Miller lay in a pool of blood, with multiple stab wounds to his face, head, chest, back, and shoulders.
The crime scene investigation revealed a chilling trail of blood leading from the kitchen to the rear hallway and exit doorknob, indicating the killers’ escape route.
Forensic experts believed the intruder might have cut himself during the attack and collected the blood evidence.

The Minnesota Bureau of Criminal Apprehension (BCA) successfully extracted a DNA profile from the blood collected at the crime scene. Unfortunately, the profile yielded no hits in the existing DNA databases, and the killer’s identity continued to elude investigators.
