The adult son of U.S. Sen. Kevin Cramer pleaded not guilty Wednesday to homicide and other charges in connection with a Dec. 6 crash that killed a North Dakota sheriff's deputy. Ian Cramer, 43, waived his preliminary hearing and entered his not guilty plea to felony charges of homicide while fleeing a peace officer, preventing arrest, reckless endangerment and fleeing an officer, as well as three misdemeanor drug charges and other low-level offenses of driving under suspension and marijuana possession. Cramer was initially charged with manslaughter, which was subsequently upgraded to the homicide count.
