Tucson was rocked by a series of bombings in 1968 at the Tucson homes of organized crime figures and a beauty salon. On July 21, dynamite exploded in the bed of a pick-up at Grace Ranch on Wrightstown Road, the Tucson home of Detroit mobster Pete Licavoli. On July 22, the patio at the home of Mafia kingpin Joe Bonanno, Sr. was bombed. On Aug. 16, two explosions – so loud they were heard heard 20 blocks away – damaged the home of Peter Notaro, a close associate of Bonanno. On Sept. 16, the Wig Beauty Salon at 2739 E. Speedway was bombed. Seventeen minutes later, the front room at the home of Robert Thomas Smith was destroyed in an explosion. Smith was a close associate of Salvatore Spinelli, another reputed mob figure in Tucson. Nobody was hurt in any of the bombings.
