The 26-year-old man found dead in his camping chair hours after attending a concert in Colorado has been identified as Trevor Jackson.

Jackson, of Salem, S.C., had ties to the Atlanta area, Officer Chris Dickey with the Commerce City police department said. The coroner for Adams and Broomsfield counties, Sherronda Appleberry, released Jackson's name and residence Wednesday morning.

Jackson had attended a Phish concert at Dick's Sporting Goods Park, the site of a three-day concert series by the band. Concert-goers were allowed to camp out on the stadium grounds, about 10 miles northwest of Denver, Dickey said.

Others campers called 911 Sunday morning after realizing Jackson was unresponsive, Dickey said. The man had been slumped over a chair in the same position for several hours, police said. Jackson was transported to University of Colorado Hospital, where he was pronounced dead.

Investigators have not released the cause of death, but foul play is not suspected.

The Colorado shows were the final stop for the group's summer tour, which stopped in June at Alpharetta's Verizon Wireless Ampitheatre.
