Jury selection is scheduled to begin Monday morning in the trial of a former FBI agent charged with vehicular manslaughter in a fatal car crash in February 2011.

Adrian N. Johnson also faces eight other charges, including driving under the influence of alcohol and homicide with a motor vehicle, for his role in the Brandywine crash, which killed Prince George's County 18-year-old Lawrence Garner Jr.

Johnson was driving north on the 10600 block of North Keys Drive when he crossed into oncoming traffic and struck Garner's vehicle head-on. Another passenger in Garner's car suffered critical injuries.

Johnson was off-duty and driving his personal vehicle at the time of the crash. He was traveling 54 mph in a 40 mph zone and had a blood-alcohol content level of more than three times the legal limit of .08, according to prosecutors with the Prince George's County State's Attorney's Office.

He was dismissed from the agency shortly after the crash.
