NASHVILLE, Tenn. (AP) -- Decommissioned police officer Donald Lawman and his wife, former Davidson County Sheriff's employee Jennifer Vardaman, are charged with obtaining prescription medication by fraud.

The 36-year-old Vardaman was named in 16 counts on an indictment returned on Tuesday, according to a news release from the Metro Nashville Police Department. Lawman, also 36, is named as a co-defendant in two counts. The drugs are believed to have been for their personal use.

Lawman was decommissioned by the police department in May 2010 because of suspicions that he was receiving excessive amounts of prescription medication.

Police Chief Steve Anderson said administrative charges against Lawman are forthcoming.

Both turned themselves in on Tuesday. Bond for Lawman was set at $20,000 and Vardaman's bond was set at $50,000.
