The uncle of a missing south Alabama teenager is going to prison for his role in an incestuous sex ring that abused children.

A Baldwin County judge sentenced 45-year-old Randall Scott Wood to three years in prison during a hearing Thursday in Bay Minette.

Wood pleaded guilty to sodomy last year. He was charged after the disappearance of his niece, 19-year-old Brittney Wood.

The teen was last seen with another uncle in 2012 and is presumed dead.

Authorities say Wood was among the victims of a group of relatives and family friends who sexually abused their own children for years.

Others also have been sentenced to prison, but authorities still don't know what happened to Wood.

Records show sentencing was delayed for another uncle who's cooperating with investigators.
