On-Camera Killing

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.

On the video, the attacker is shown following the 48-year-old woman off the bus and walking alongside her for a moment, before shooting her and running off.
