Austin must do his time in a federal prison because he was on probation for a federal firearms conviction when he committed his latest offense and his probation was revoked.
He will serve state and federal sentences concurrently.
Austin's attorney, Scott M. Anderson, said Austin raised the woman's two boys and doesn't want to lose contact with them.
“While he was here he wanted to be able to make plans for a future with her,” Anderson said.
Marrying their mother was the only way the children would be able to visit Austin in federal prison, Anderson said.
Austin, his left arm in a cast, fumbled with a purple paper ring when it came time to slip it on Trojack's finger. But he knew what to do when told to kiss the bride.
Allen didn't get to enjoy his married status very long.
Federal authorities were waiting to take him to prison.
