The body of a Lanikai man missing since June 30 was found today below the Pali Lookout.

Police tentatively identified the body as Steven Thomas, 36, the millionaire founder of an Internet software security company.

Firefighters were called to assist police with a body retrieval at 1:30 p.m., said Honolulu Fire Department Capt. Frank Johnson. The decomposing body was found by three hikers today on the Windward O'ahu side of the Pali Tunnel.

Firefighters hiked down and brought the body up to Pali Highway at 3:30 p.m.

Thomas was diagnosed with bipolar disorder in April, and was anxious about the poor performance of his investment portfolio and discussions about moving back to Colorado full-time, his wife, Candis Burton Thomas, said at a news conference last week.

Candis Thomas said she and her husband, who controls a fortune estimated at $50 million, were scheduled to return to their summer home in Boulder, Colo., on June 27.

On June 26, Steven Thomas, creator of Webroot Software, the company that created the Spy Sweeper and Window Washer programs, packed a suitcase and said he was going to stay with his mother and cousin at the Princess Kaiulani Hotel. Thomas was last seen at the Waikiki hotel on June 30 at 5 p.m.
