The Idaho Statesman reports 38-year-old Rodney Wayne Bibbey initially told police that his wife was changing the oil in her car when the jack slipped. An investigation determined the April 2012 death of 35-year-old Trina Bibbey was a homicide.
Rodney Bibbey of Marsing pleaded guilty to second-degree murder Oct. 21 in a plea agreement that reduced the first-degree murder charge.
Bibbey is scheduled to be sentenced Dec. 23 in that case and for an injury to a child conviction that initially was charged as sexual abuse of a child under 16.
