Philadelphia police say arrest made in videotaped killing
Philadelphia police say they've charged a suspect with a killing caught on surveillance cameras. Videotape shows a man shooting Patricia McDermott in the head as she walked to work before dawn in mid-May.
Officials say the suspect is a subcontractor at the hospital where McDermott worked as an X-ray technician. Police say they have video of Juan Covington at Pennsylvania Hospital shortly after the shooting, wearing clothes matching those worn by the killer. A homicide detective says he's unsure if the victim even knew the suspect.
Investigators released tape shot from cameras mounted on several buildings in the hope someone would recognize the killer.
