Christina Schuster, 34, was found dead in her apartment at River Place Apartments in Oconomowoc, Wisconsin, on September 5, 2016. Her brother discovered her body; investigators determined she died of a single gunshot wound to the head and the death was ruled a homicide. No weapon was recovered at the scene.

Authorities identified a male friend as a person of interest and noted Schuster’s vehicle was missing from her residence. Investigators focused on 40-year-old Jessie Lee, described as Schuster’s on-again, off-again boyfriend. Her brother told police she had planned to end the relationship and had seen Lee with a firearm. He was charged in her death and later sentenced to life in prison.

Does anyone have information about Schuster’s movements in Oconomowoc in the days before September 5, 2016?
