A Topeka man accused of killing a passenger when he lost control of his truck says he was suffering from post-traumatic stress disorder from his time as a US Navy SEAL.

Glenn Triebwasser was convicted of involuntary manslaughter under the influence of alcohol last month. He also was convicted of driving on a suspended license, failure to maintain a single lane and a seat belt infraction.

He was behind the wheel of the truck when it rolled over on Interstate 70 in Topeka last year, killing 40-year-old Billie Jo Baldwin of Meriden.

His lawyers are arguing Triebwasser should be given a shorter sentence.

But the Naval Special Warfare Center in Coronado, California, says his name doesn't appear in the Navy's records of SEALs. Coronado is the primary training facility for the SEALs.
