According to Mark Howerton, on Sunday, October 29, 2017, the couple left Mala Luna sometime between 5 and 6 p.m. They got in an argument after seeing Cayley’s ex-boyfriend, Jett Birchum, at the festival.
Howerton said they continued to argue in the car, but eventually stopped at a gas station to have “rough” make-up sex. Howerton would later tell police that shortly after sex, Cayley stopped breathing. That’s when he rushed her to the nearest emergency room.
