According to an informant shortly after he became boss, DeSimone supposedly raped the wife of his underboss, Girolamo "Momo" Adamo, in front of her husband. The humiliated "Momo" later shot his wife and committed suicide in their San Diego home. Marie Adamo survived her wounds and later married Frank Bompensiero. It is uncertain if DeSimone actually committed the actions that caused "Momo" to kill himself. By all accounts DeSimone was a straight-laced and sober character.
