The Arizona Republic
June 3, 2001
June 2, 1976 - Bolles, 47, is gravely wounded when six sticks of dynamite are detonated beneath his compact car in the parking lot of the Hotel Clarendon, 401 W. Clarendon Ave. Bolles, who had been lured to the hotel by the promise of a news tip, whispers the name "Adamson" to his rescuers.
June 13, 1976 - Bolles dies. Phoenix Police arrest John Harvey Adamson, racing-dog owner and a former tow-truck operator.

July 6, 1977 - Trial begins for Dunlap and Robison, who are charged with first-degree murder. During the trial, Dunlap's attorney tries to cast suspicion on Phoenix attorney Neal Roberts, who had dealings with both Adamson and Dunlap, as the real mastermind in the murder plot.
Nov. 6, 1977 - A jury finds Dunlap and Robison guilty primarily on the strength of Adamson's testimony. They also are found guilty of conspiring to kill then-Arizona Attorney General Bruce Babbitt and advertising man Al Lizanetz.

March 22, 1993 -An attorney for Dunlap, John Savoy, is sentenced to two years' probation on perjury conviction for telling a grand jury he didn't have any records dating from 1977 related to Dunlap.
