A memorial service will be held tonight for the 22-year-old Howard University student killed last week in Northwest D.C.

Friends of Omar Sykes and members of the Howard community are invited to attend the service at the Andrew Rankin Memorial Chapel at 6 p.m. tonight, according to the university’s president Dr. Sidney A. Ribeau.

Mayor Vince Gray is expected to speak at the service, NBC4 reports.

Sykes, a junior marketing major, was shot multiple times on July 4 during what police believe was a “random encounter” on the 700 block of Fairmont Street NW. Another Howard student was beaten during the attempted robbery and treated for non-life threatening injuries.

The suspects in the case are still at-large. One suspect was described by police as about 5-foot-10-inches, weighing 210 pounds and wearing all black the night of the murder. The second was described as about six feet tall and wearing a white shirt. Police are offering a $25,000 award for tips that lead to an arrest.
