Dave Brockie, frontman of the theatrical metal band GWAR, died of an accidental heroin overdose, the Virginia coroner’s office said Tuesday.

According to The Associated Press, an administrator at the chief medical examiner’s office announced that Brockie’s cause of death was acute heroin toxicity. Known by the stage name Oderus Urungus, Brockie was found dead in his Richmond home on March 23. He was 50.

Brockie was an original member of GWAR, which formed in 1984. The grotesquely costumed band known for its over-the-top showmanship earned a Grammy nomination and often appeared on MTV’s Beavis and Butt-Head.

GWAR’s most recent album, Battle Maximus, was released last September. The band had recently toured Australia and Japan.

GWAR has set up the Dave Brockie Fund, a charity aiming to promote “the advancement of music, images, letters and performances in the arts” with the intention of supporting artists “who cannot find funding through mainstream channels.”

In 2001 the band lost another member, 34-year-old lead guitarist Cory Smoot, who was found dead on the band’s tour bus. Smoot, aka Flattus Maximus, died of coronary artery thrombosis.
