Bobby Gene Martin’s brushes with law enforcement for driving drunk date to 1981. But this week, his more than 30-year streak of DWI arrests came to an abrupt end.

A Texas jury convicted the 64-year-old of his 10th drunk driving offense along with a retaliation charge for threatening to harm the arresting officer and his family. They gave him two life sentences.

The jury came back with its guilty verdict after three hours of deliberation. And throughout the proceedings, the jury had no idea that Martin had already been arrested nine other times for drunk driving. The jurors only  knew that this was at least his third.

“You could see they were actually shocked that he’d had 10 DWIs and was still out and about driving around,” Montgomery County Assistant District Attorney Kyle Crowl said.
