An autopsy report shows three-time world surfing champion and Kauai native Andy Irons had drugs in his system when he died of a heart attack in a Texas hotel room last year, according to the New York Times.

In the hotel room where Irons was found dead, police discovered prescription bottles for anti-anxiety medication, a sleep aid, and tablets containing methadone, a painkiller used to treat opiate addiction.

The confirmation of drugs in Irons’ system comes on the same day that his family released a statement listing the primary cause of death as a heart attack related to coronary artery disease, and a secondary cause as “acute mixed drug ingestion.”

The statement reads in part:

“The family apologizes for the delay in the release of this information. The injunction filed last December was to allow Andy’s widow, Lyndie, who was then eight months pregnant with Andy’s son, Andy Axel Irons, to give birth in peace. Please understand that this decision meant that the family did not learn the cause of Andy’s death until May 20th, and only after a second delay was requested by an attorney in Dallas, without the family’s knowledge or consent, to provide time for the 13-page toxicology report to be interpreted by two independent forensic experts — a process that took several weeks, but also enabled the family to fully come to terms with the unexpected root cause of Andy’s death.”

The New York Times reports it obtained a copy of the autopsy report, prepared by the Medical Examiner’s office in Tarrant County, Tex., which won’t be made public until June 20.
