BISMARCK, N.D. (AP) The 42-year-old son of U.S. Sen. Kevin Cramer was charged Thursday with manslaughter and fleeing an officer after a police pursuit ended in a crash that killed a North Dakota sheriffs deputy who had just laid a tire deflation device on the road and was taking cover behind his squad car, according to court documents.

Ian Cramer, of Bismarck, was traveling over 100 mph and already had two flat tires when he slammed head-on into Deputy Paul Martins squad car on Wednesday, pushing it directly into Martins person and launching him for about 100 feet, according to charging documents. Martin, 53, was killed.

Ian Cramer is scheduled to make his first court appearance Friday on multiple felony counts including manslaughter, fleeing a police officer and reckless endangerment. Court records did not list an attorney for him, and Sen. Kevin Cramer declined an interview after charges were filed out of respect for Martins family.

Earlier Thursday, Cramer released a statement saying: We ask the public for prayers for the lost officers family and colleagues who serve us every day and are grateful for all they do for us.
