On the night of April 3, 2012, 26-year-old Lauren Donelson was shot through the chest after stepping toward her apartment door on the 8700 block of West Mill Road in Milwaukee to investigate her car alarm. She had armed herself with a revolver before opening the door; the single gunshot struck her and proved fatal when she stumbled back into the apartment.

Her 34-year-old roommate reported hearing the shot and later called 911, but investigators say the roommate first called Donelson’s boyfriend and waited at least 15 minutes before contacting emergency services. Police also learned the roommate initially refused a search; after obtaining a warrant they found nearly $3,600 in cash, over 160 grams of marijuana, and a digital scale. The boyfriend was jailed on unrelated charges, including bail jumping and possession of a firearm by a felon. No one has been charged in connection with Donelson’s killing.

The homicide remains unsolved. Anyone with information about that night or who saw suspicious activity near the building is asked to come forward.
