A Ventura woman died Sunday after attending a music and art festival in Monterey County, authorities said.

Baylee Ybarra Gatlin, 20, was pronounced dead just after 3:40 a.m. at Twin Cities Community Hospital in Templeton, said Sgt. Jay Wells, of the San Luis Obispo County Sheriff's Office.

Gatlin had arrived at the Templeton hospital via ambulance at 2:12 a.m. after attending the Lighting in a Bottle Festival held on the shores of Lake San Antonio in Bradley, according to a news release from the sheriff's office.

Wells said Gatlin's family had been notified and as of Tuesday morning an autopsy was scheduled for Wednesday.

The San Luis Obispo County Sheriff's have jurisdiction over the investigation as the 20-year-old died at Twin Cities Hospital, Wells said. However, the Sheriff's Office of Monterey County will be investigating the events at the Lighting in a Bottle Festival, Wells said.

The festival, billed as an all-ages and drug-free event, was held Wednesday through Monday. According to the Lightning in a Bottle website, medical resources were available for attendees on site.
