Shirley Ann Lacks was 27 when she was fatally shot on the evening of September 5, 1990, in Colorado Springs. She was with a male friend, parked in his white 1977 Lincoln Continental Mark V near Rio Grande and Nevada streets, when an unknown assailant approached and fired two shots through the open driver’s side window. One bullet missed the man; the other struck Lacks in the arm, then penetrated her heart. She was taken to Saint Francis Hospital and died that same day.

Police learned officers had responded three days earlier, on September 2, to an altercation at a Sheldon Street residence where a woman later identified as Lacks appeared to have been assaulted, but she was not interviewed then. Investigators developed information that Lacks was involved in prostitution and narcotics and received a tip about a gray Mazda consistent with a witness report of a Mazda RX7. The friend at the scene could not give a detailed description of the shooter, and no arrests have been made. The homicide remains unsolved with the Colorado Springs Police Department.

Did anyone in the area that night or who knew Shirley have information that might help explain what happened?
