Kenneth Bush, a 33-year-old White man, was shot and killed during a violent home invasion on March 20, 1987, on the north side of La Crosse, Wisconsin. He was one of three people slain in the house; his mother, Lila Bush, and his girlfriend, Debra Reget, were also attacked and killed after an intruder entered through a basement window and forced his way upstairs. About $1,500 was taken and the killer fled in a vehicle belonging to the victims.

Investigators linked the crime to Michael Tenneson. Forensics included a footwear impression on the kitchen linoleum and .25-caliber bullets recovered at autopsy; witnesses placed Tenneson with a Raven .25-caliber pistol and buying shoes matching the tread. The stolen vehicle was found near Madison, and Tenneson was later located in Colorado under an alias after being connected to two additional homicides. He confessed to the La Crosse killings on May 25, 1987.

Tenneson pleaded guilty to three counts of murder in Wisconsin and received three life terms to follow lengthy Colorado sentences. Does anyone have information about Kenneth, Lila or Debra’s lives before 1987 that could add context to the case?
