According to booking records, the 25-year-old man arrested on drug charges after he was found to have hallucinogenic mushrooms during a rescue is Jon Robert Schuttenberg, 25, of St. Charles, Mo.

Officials say Schuttenberg called 911 Friday afternoon after his friend -- who was half-naked and possibly high on mushrooms -- needed to be rescued from the First Flatiron. Boulder County Sheriff's Office deputies found the mushrooms on Schuttenberg after the rescue, they said.

Schuttenberg remains at the Boulder County Jail. Bail is scheduled to be set Monday.

Investigators have not yet said if they will be pressing any drug charges against the friend who was rescued.
