A former Colorado police sheriff, who was once named national “Sheriff of the Year,” pleaded guilty Tuesday to charges of trading methamphetamine for sex with a male prostitute.

According to KUSA-TV, 69-year-old Patrick Sullivan confessed to a felony drug possession charge and a misdemeanor charge for soliciting a prostitute.

Sullivan was caught in an undercover sting operation last November after going to a home in Aurora, Colorado to trade meth for sex with a male prostitute. Deputy Attorney General Michael Dougherty said Sullivan’s actions during the sting, such as undressing after throwing the meth on the bed, revealed that Sullivan committed the practice multiple times before.

Dougherty lambasted Sullivan, saying he was “a man who’s brought disgrace upon himself and law enforcement” and “a disgrace to the badge.”

The former sheriff, who already spent eight days in prison, will serve the remainder of his 38-day sentence in a jail named after him in Arapahoe County, Colorado.

“I apologize to the court, to the community, to my family,” Sullivan said. “There is no excuse for my behavior.”

Sullivan served as sheriff for Arapahoe County from 1984 until 2002 and was named the “Sheriff of the Year” by the National Sheriff Association in 2001.
