Drugs or alcohol may be the cause of the 24-year-old's death.
An Oakland woman, 24, died Thursday afternoon at an area hospital after collapsing at the Coachella Valley Music and Arts Festival on April 12.
"We're testing to find out whether drugs or alcohol are involved in the death," said Sgt. Curt James of the Riverside County sheriff-coroner's office to The Hollywood Reporter. James could not confirm that it was an overdose related death and won't know the cause for up to six weeks.
