The Hawaii medical examiner identified a body found at the bottom of an Oahu cliff as that of Steven Thomas, 36, the founder of security software maker Webroot Software Inc. Thomas had been missing since June 30 when he went to a hotel to visit relatives, the Honolulu Advertiser reported.

Officials said Thomas' decomposing body was found by three hikers Sunday afternoon below the Nuuanu Pali Lookout, a 985-foot cliff.

Thomas had been diagnosed with bipolar disorder in April after an incident in which he ran naked into a group of competitive runners passing in front of his Lanikai, Hawaii, home. His wife told the newspaper Thomas had experienced delusions of being stalked by aliens and the government but had refused medical help.

He disappeared as the couple was planning to travel from Hawaii to their summer home in Boulder, Colo., where Thomas founded his software company and later sold it for $50 million.
