Arlington County authorities are investigating the death of a man last week after police used a stun gun to subdue him.

Thirty-six-year-old William Bumbrey III died Jan. 18 after being arrested on suspicion of shoplifting near the Pentagon City Metro station.

Detective Crystal Nosal, a spokeswoman for the Arlington County police, says Bumbrey became combative and uncooperative and continued to fight with the officers after they used the stun gun. He died a short time later after being taken to a hospital.

Bumbrey's family says he had serious medical problems and was addicted to PCP. The family has hired a lawyer who specializes in stun gun cases and wants police to release a video of the incident.

Police say they can't release the video because the case is still under investigation.
