Los Angeles police are investigating the death last week of former ''Angel'' star Glenn Quinn, the Los Angeles Times reports. The actor was found dead at a friend's home in North Hollywood on Tuesday. Detectives told the Times that they believe the 32-year-old died of a drug overdose, and that the case would remain open pending the completion of toxicology tests. Police say they do not suspect foul play.
Quinn played the half-demon Doyle throughout the first season of ''Angel'' in 1999, until his character was killed off and written out of the show. Before that, the Irish-born actor had a recurring role on ''Roseanne,'' playing Mark Healy, the dimwitted husband of elder daughter Becky, from 1990 to 1997.
