Prince George’s County State’s Attorney Glenn Ivey took to the courtroom floor Tuesday, a rare step saved for the most egregious of crimes, Ivey’s spokesman Roman Korionoff said.

On trial is Robert Washington Francis, 20, who, along with 21-year-old Robert Tyrone Stamp, is accused of being involved in a March 2007 drive-by shooting in which a bullet missed its intended target and killed Theodora Summers, 40, as she was getting ready for work. At the time, police said people were standing on a driveway around 5:15 p.m. on the 6700 block of 96th Avenue in Lanham when occupants in a vehicle opened fire, striking a 24-year-old man in the hip. The shots were the result of an ongoing dispute.
