DENVER, Colo. -

A former Arapahoe County sheriff convicted in a meth-for-sex case has pleaded guilty to violating his probation.

Patrick Sullivan pleaded guilty Thursday to leaving the state without permission three times this year. He could face prison time and fines time when he is sentenced next month.
    
The 71-year-old was sentenced in 2012 to 38 days in the jail once named for him. He was placed on two years' probation after pleading guilty to possession of methamphetamine and soliciting for prostitution.
    
Authorities say he also violated probation by testing positive for meth use several times between September and May and for alcohol four times between April 2012 and August. The judge ordered further investigation on those charges before Sullivan is sentenced on June 19.
