Three-time world surfing champion Andy Irons died Tuesday. He was 32.

Irons contracted an illness in Portugal in October and missed his Round 1 and 2 heats at the Rip Curl Search Puerto Rico stop on the ASP Men's World Tour on Saturday. He was traveling back home to Hawaii when, on an overnight layover in Dallas, was found by staff at the Grand Hyatt Hotel at the Dallas/Fort Worth International Airport after he failed to respond to a wakeup call.

A police report released Wednesday said the prescription drugs Xanax, an anti-anxiety medication, and the sleeping aid Ambien were found in Irons' hotel room. There were no signs of trauma and foul play.

An official statement by Billabong, one of Irons' sponsors, said he was suffering from Dengue Fever. "He fell ill in Puerto Rico and went to see the contest doctor," said Stephane Tenailleau, European spokesman for Billabong. "The doctor told him to withdraw from the contest and go back home to fix the disease."

Tarrant County Medical Examiner Nizam Peerwani said a ruling on the cause of death could take several weeks, pending the completion of lab tests.

A report in the Honolulu Star Advertiser, citing the same medical examiner, said that Irons' death is being investigated as a possible methadone overdose and reported the drug was found along with other prescription drugs at the scene.
