PHILADELPHIA (CBS) — Philadelphia police have identified the third suspect wanted in a violent home invasion robbery near Temple University in which four women were bound with duct-tape and robbed at gunpoint (see related story).

The incident happened on March 4 around 7:30 p.m. along the 1800 block of North 18th Street.

Police say 24-year-old Elijah Washington, along with two other men followed a 21-year-old Temple student to her off-campus apartment as she left the subway station at Broad Street and Cecil B. Moore Avenue. At her home, the suspects forced the victim back into her apartment at gunpoint before duct-taping her and her three roommates.

The suspects then took cellphones, cash, computers and debit cards before leaving the women bound in the apartment.

Two of the suspects, Tyree Johnson, 19, and Malcolm Murray, 18, were taken into custody the next day, but Washington has been on the run since (see related story).

Police believe Washington may be in the area of the Wilson Park Housing Development at 25th and Jackson Streets or Southwest Philadelphia in the area of 52nd and Pentridge Streets.

Anyone with information on his whereabouts should call the Philadelphia Police Department’s Central Detective Division at 215-686-3093 or 9-1-1.
