An actor who was best known for his role on the 1990s sci-fi series “Babylon 5” has died. TMZ.com reports that Jerry Doyle died Wednesday.

“Sources tell us … a call was made to his Las Vegas home yesterday afternoon after he was found unresponsive,” TMZ reports. “It’s unclear how the political radio talk show host and actor died … but we’re told no foul play is suspected. An autopsy is pending.”

Doyle hosted the nationally syndicated “Jerry Doyle Show” on Talk Radio Network, expressing his right-libertarian political views. Before he went into acting, he was reportedly a jet pilot and a Wall Street stockbroker.

On “Babylon 5,” TMZ notes, “Jerry starred as security officer Michael Garibaldi from 1994 to 1998 and was married to co-star Andrea Thompson from 1995 to 1997.”
