^†The two other burglaries mentioned by the CIA referred to a break-in at the Summa headquarters in Las Vegas, where files were rifled, and at the Encino offices of Bill Gay and other Hughes executives, where a telephone scrambler unit was stolen. Companion units of the scrambler—a device that garbles telephone conversations to foil eavesdroppers—were at the CIA headquarters in Langley, Virginia, and the Robert Mullen Company offices, the CIA front operated by Hughes’s Washington representative Robert Bennett. If the conversations between Hughes executives in Encino and the CIA operatives in Langley and Washington had been recorded by an electronic eavesdropping device, the recordings could be replayed through the scrambler, deciphered, and transcribed. It was later established that the scrambler was stolen by two associates of Robert Hall, a Los Angeles private detective, drug dealer, and wiretap specialist who at one time had performed bugging services for fugitive financier Robert Vesco. The burglars gave the stolen Hughes scrambler to Hall—who had a private library of hundreds of explosive conversations that had been secretly recorded. Hall, in turn, passed the scrambler to an old acquaintance, Vincent Kelley, the Hughes security chief at Encino. Two years later, in July of 1976, Hall was found murdered in his Burbank apartment. His two associates, who had stolen the Hughes-CIA scrambler, were later convicted.
