The procurement boss for the District's Department of General Services was arrested and charged with drunken driving after police said he was discovered sleeping in a parked car with an open wine bottle on a workday.

Jerry Wayne Lanum, 65, was charged last fall with driving under the influence and operating a vehicle while impaired, according to D.C. court documents. On Friday, a judge dismissed the case when prosecutors were not ready to proceed. The case was refiled Tuesday, and arraignment has been scheduled for Feb. 20, according to Ted Gest, a spokesman with the Attorney General's Office.

According to court documents, at about 3 p.m. on Sept. 21, 2012, a parking enforcement officer found Lanum asleep in his car parked in a "No Standing Anytime" zone outside the Reeves Center, where the Department of General Services is headquartered. The enforcement officer wrote a ticket and tried to wake Lanum up. Lanum became "irate and started to yell and curse," according to a police report.

Police officers arrived at the scene. They spotted keys in the vehicle's ignition and noted that its engine was running. Officers also discovered an open bottle of white zinfandel under the floorboard on the passenger side, according to the report.

Asked whether he had been drinking, Lanum told officers, "I had one about a half-hour ago." Lanum failed a number of sobriety tests, at which point officers arrested him, police said.

As of Tuesday afternoon, Lanum remains an employee at the Department of General Services, according to Darrell Pressley, a spokesman for the department.

Lanum was hired on July 21, 2008 as an associate director for contracts and procurement, according to the District's website. His annual salary is $140,000.

The Department of General Services oversees many of the city's construction projects and environmental initiatives.

On Oct. 10, 2012, Lanum pleaded not guilty to the charges and was ordered to report for alcohol testing and treatment. On Jan. 25, the case was dismissed by the court after prosecutors failed to act.

Lanum has had past legal trouble involving alcohol. On Jan. 4, 2012, Lanum was charged with possessing an open container of alcohol. A judge dismissed that charge after Lanum completed a diversion program, according to court documents.

Lanum did not respond Tuesday to requests for comment.
