After deliberating for more than 48 hours, a jury has found Kim Walker guilty of manslaughter in the shooting death of his daughter's boyfriend.
Walker was charged with second-degree murder in the 2003 death of 24-year-old James Hayward.
A Yorkton court heard Walker's daughter, Jadah, started using drugs after moving in with Hayward, and that Walker feared for her life and his own.
Crown prosecutor Robin Ritter argued Walker took deliberate steps before going to Hayward's home with a loaded handgun and firing 10 bullets, hitting him five times.
Walker's lawyer, Balfour Der, argued the shooting was an act of self-defence.
The trial is Walker's second on the charges. He served 3 1/2 years in prison before a retrial was ordered.
Walker faces a four-year minimum jail term, but the defence is asking for time served.
