KINGMAN, Arizona - A 50-year-old Kingman man who twice ran over his stepdaughter's boyfriend in front of the boyfriend's home has accepted a plea deal just days before his trial on charges of first-degree murder and other crimes.
Michael Anthony Rivera pleaded guilty Tuesday in Mohave County Superior Court to second-degree murder in the death of Nicholas Gerenscer, 23, and to attempted murder of Gerenscer's father, who witnessed his son's November 2011 death.
There was bad blood between the families of Rivera and Gerenscer, but the circumstances of what led to the killing remain in dispute, the Kingman Daily Miner reported.
Rivera told police the killing was an accident, but witnesses said Rivera had been driving up and down the block and that there was yelling and gestures by those involved.
Gerenscer was in the backyard when he heard a commotion in the street involving his father and brother. He jumped a fence and was standing in the street when he was hit the first time.
Gerenscer was prone on the ground when he was struck the second time after Rivera turned the car around.
Rivera's plea agreement calls for a 20-year prison term on the second-degree murder charge.
Rivera also faces a lesser prison sentence on the attempted-murder conviction, but it would run at the same time with the murder conviction's sentence, Prosecutor Bob Moon said.
When Rivera is sentenced Sept. 5 by Judge Steven Conn, he will have already served about two years and nine months.
