St. Cloud, Minnesota - Republican Jeff Johnson suspended his campaign to become Minnesota's governor after his daughter was stabbed to death on Friday night.

Johnson's 22-year-old daughter, Hallie Marie Tobler, was reportedly found dead on Friday night inside the apartment she shared with her husband in St. Cloud.

Hallie Tobler reportedly died from "multiple stab wounds" and was found alongside her husband, who had suffered life-threatening wounds that local police currently believe were self-inflicted.

Local authorities suspect that the incident was an attempted murder-suicide involving her husband, who is currently in police custody while receiving treatment in hospital.
