Master Patrol Officer Brian T. Gibson, 27, was murdered while on duty in Washington, D.C., in the early hours of February 5, 1997. He was seated in his marked patrol car at a traffic light at Georgia Avenue and Missouri Avenue NW, outside the IBEX Nightclub, when someone approached and fired multiple shots. Four bullets struck Officer Gibson—one in the shoulder and three to the left side of his head—causing his immediate death. He was calling in a suspicious tag number at the time of the attack.

The assailant, Marthell Nathaniel Dean, had been ejected from the nightclub shortly before the shooting. Officers from the Fourth District apprehended Dean about three minutes after the shots were fired as he tried to flee. Brian Gibson had served six years with the Metropolitan Police Department and left behind a wife and two children; colleagues described him as likeable, respectable, and professional. On February 18, 1998, Dean was found guilty of first-degree murder and was later sentenced to life without the possibility of parole.

Did anyone who frequented the IBEX Nightclub in 1997 have details about that night or remember seeing anything that could shed more light on the events leading up to the shooting?
