Republican North Dakota Sen. Kevin Cramer’s adult son has been charged with homicide for his alleged involvement in ahigh-speed chase that killed a sheriff’s deputy earlier this month. 

Ian Matthew Cramer, 42, was initially facing a manslaughter charge over the Dec. 6 head-on crash that resulted in the death of Mercer County Sheriff’s Deputy Paul Martin, but a judge on Thursday approved upping the charge to homicide, which comes with a maximum 20 year prison sentence if Cramer is convicted.
