While being questioned by Swansea police, Busch told police he has a concealed carry permit in Missouri and had a loaded gun in his pocket. Busch gave police permission to search the helicopter, where they found three more loaded handguns and a pepper spray gun, court documents say.

Several types of prescription drugs also were recovered, the documents noted. Some were prescribed to Busch and others to the woman who was with him, identified in court documents as Dawna M. Wood.

Busch told police he had the drugs to treat his anxiety issues, police said.

Wood is a secondary subject of Graham’s letter, which states that police reports “will include sensitive and private information regarding Dawna M. Wood (a person not under investigation) ... That would obviously be private health information that would clearly be protected from release under HIPAA.”

Busch was held by Swansea police overnight on suspicion of reckless conduct, unlawful use of a weapon and being intoxicated “in or about an aircraft.” He was released shortly after noon July 11.

Busch, 53, is the former head of Anheuser-Busch Cos. and ran the brewing giant from 2006 until it was bought out two years later.
