David Houghton

David Houghton was a small-time criminal and a friend of Myles Connor. Connor claims Houghton robbed the Gardner Museum with Bobby Donati and a third accomplice. After the heist, Houghton flew to California to visit Connor in prison, so claims the art thief, and told him they planned to use the valuable paintings to negotiate him a reduced sentence. If Houghton was involved, it's almost impossible to imagine he was one of the two men dressed as cops who duped the guards; he was more than 300 pounds and doesn't match the descriptions of the thieves. He died of a heart attack in 1991 — the year after the heist.
