UPDATE: The Virgina medical examiner’s office has ruled that Dave Brockie’s cause of death was a heroin overdose, according to the Associated Press on Tuesday.

PREVIOUS: The frontman of heavy metal band Gwar, Dave Brockie, also known for his band name as Oderus Urungus, died Sunday at the age of 50. Band manager Jack Flanagan confirmed the news with a statement Monday.

“It is with a saddened heart, that I confirm my dear friend Dave Brockie, artist, musician, and lead singer of GWAR passed away at approximately 6:50 p.m. EST Sunday, March 23, 2014,” Flanagan said. “His body was found Sunday by his bandmate at his home in Richmond, VA. Richmond authorities have confirmed his death and next of kin has been notified. A full autopsy will be performed. My main focus right now is to look after my bandmates and his family. More information regarding his death shall be released as the details are confirmed.”

Cause of death has yet to be determined, though foul play is not suspected at this time.

Brockie founded the group, known for their outlandish costumes and purposely offensive lyrics, in 1984 with Hunter Jackson.

“Dave was one of the funniest, smartest, most creative and energetic persons I’ve known,” former Gwar bassist Mike Bishop told Richmond outlet Style Weekly, who first reported the news. “He was brash sometimes, always crass, irreverent, he was hilarious in every way. But he was also deeply intelligent and interested in life, history, politics and art.”

Before founding Gwar, Brockie played in punk band Death Piggy, where he met Jackson, who created props for the band. They created satirical group Gwaaarrrgghhlllgh before eventually shortening it to Gwar and releasing their debut album “Hell-O” in 1988.

Gwar quickly developed a cult following as they posed as alien warriors sent to dominate the human race. The band released several albums, including 1990’s “Scumdogs of the Universe,” 2004’s “War Party” and 2010’s “Bloody Pit of Horror.” Their most recent album, “Battle Maximus,” was released last year.

The metal band has also been nominated for two Grammys, and celebrated their 30th anniversary this year. Brockie’s death marks the second one in the past few years for Gwar. Guitarist Cory Smoot, also known as Flattus Maximus, was found dead in 2011.
