The cause of death for Shock G, the frontman of rap group Digital Underground, was revealed to be an accidental overdose of fentanyl, methamphetamine and alcohol, Billboard reported Thursday.
The late rapper was last seen alive at a hotel in Tampa, Florida, but was later found unresponsive on April 22 by the hotel’s manager, who looked in on the performer after he had missed his checkout time.
Shock G, born Gregory Jacobs, was pronounced dead at the hospital that day at age 57, but a rep for the medical examiner’s office said the final autopsy hasn’t been completed yet at the time.
The rap group is best known for the 1990 hit “The Humpty Dance,” which reached the top of the Billboard rap singles chart. The iconic music video is rapped by Shock G’s fake-nosed alter-ego Humpty Hump.
Shock G started the eccentric Oakland, Calif.-based group, which once featured famed rapper Tupac Shakur, in 1987. Shakur made an appearance in the group’s “Same Song,” in which he rapped the final verse.
Shock G’s death was first confirmed by the group’s co-founder Chopmaster J in a post on Instagram.
