A Nacogdoches County Jury determined that an East Texas man will serve 19 years in prison after being found guilty of intoxicated assault. His name is William Overturf. He caused a serious accident. Tuesday was the two year anniversary. Justin Sowell had a head on collision when Overturf's vehicle came into his lane on a narrow bridge. Sowell, who was 18 at the time, attributed a seatbelt for saving his life. Overturf received 19 years in prison plus a $10, 000 fine.
