City of Oconomowoc - Christina Schuster, 34, was killed by a single gunshot wound to the head, police Chief Dave Beguhn said Wednesday afternoon. Schuster was found dead in her Oconomowoc apartment Monday morning, Sept. 5.

Authorities are searching for a man who had an on-again, off-again friendship with Schuster, Beguhn said. The man is not from the area, and Schuster's vehicle is missing, Beguhn said.

Police said that at about 10:22 p.m. they responded to the scene of a suspicious death in the 1200 block of West Wisconsin Avenue. Schuster's brother found her deceased at their residence.

“At this time the scene is being investigated as a homicide. We are currently working with Waukesha County Sheriff Department, the district attorney and the Medical Examiner’s Offices. This is an ongoing investigation,” Beguhn said earlier.

Police did not release the make or model of the missing vehicle or the identity of the man.
