HALAWA, OAHU (HawaiiNewsNow) - A former Big Island police sergeant convicted of kidnapping and murdering his wife has died in prison.
Officials said Kenneth Wayne Mathison died Sunday at the Halawa Correctional Facility at the age of 63. Authorities do not suspect foul play.
In 1992, Mathison was accused of beating his wife, Yvonne Mathison, with a pipe and running her over with a van to make it look like an accident. He was sentenced in 1996 to life in prison with possibility for parole for the murder, and 20 years for kidnapping.
