Last weekend marked the annual Camp Bisco Festival, with hosts The Disco Biscuits welcoming thousands of fans and dozens of performers to Montage Mountain in Pennsylvania. While most fans enjoyed the music of artists like Lettuce, STS9, Odesza, Zed’s Dead, Lotus and more, one individual seemingly had a hard time over the weekend.

When the festival ended last Saturday, a 20-year-old attendee named Collin Burns from New Jersey was reported missing on the following day. Burns, whose father is Lt. John Burns, was last seen Sunday morning at a music festival in Scranton. Authorities eventually located the man, and, according to NBC 10 Philadelphia, he was found in a nearby swamp, “buried to his waist in water and mud.”

While Burns was taken to a hospital, authorities reported that he was alert upon discovery. The news report ends with the most telling line of all: “It wasn’t immediately clear how Burns ended up in the swamp.”
