The cause of death is not yet confirmed, but no foul play is suspected. An autopsy is pending.
Doyle's biggest acting credit was as Garibaldi, the recovering alcoholic security chief on the space station Babylon 5 for five seasons from 1994 to 1998. Before he began acting, he worked as a corporate jet pilot and a stockbroker.
After Babylon 5, he transitioned into conservative talk radio, and hosted the nationally-syndicated The Jerry Doyle Show on the Talk Radio Network. He also founded the news website EpicTimes.
Doyle was born July 16, 1956, and grew up in Brooklyn. He was married to his Babylon 5 costar Andrea Thompson from 1995 to 1997.
