Authorities say 24-year-old Elijah Washington may be in the area of the Wilson Park Housing Development located at 25th and Jackson streets or in Southwest Philadelphia in the area of 52nd and Pentridge streets.
The robbery and home invasion took place at approximately 7:30 p.m. on March 4th.
A 21-year-old Temple student was forced into her home by one gunman and his two accomplices rushed to the third floor to where the student's roommates were located.
"He had the gun to my head the entire time," the victim told Action News last week. "His friend said, 'Just be quiet. Shut her up. We won't hurt you if you just shut up.' And that's when he got out the duct tape."
Three of the four women were bound. The suspects stole cell phones, cash, credit cards and computers and then fled.
"They were leaving. They said, 'You wait 30 minutes, don't say anything. You didn't see us or we will kill you. We know where you live,'" she said.
Police captured two of the suspects, Tyree Johnson and Malcom Murray.
Anyone with information on the whereabouts of Elijah Washington should contact Central Detective Division 215-686-3093 or dial 911.
