On 29 January 1983, Casillo was murdered by a bomb planted under the pedal of his car, next to the
SISMI Forte Boccea in
Rome.
Pasquale Galasso, chief of the
Galasso clan and member of the rival
Nuova Famiglia headed by
Carmine Alfieri, was responsible for the blast. This was one of the first times that a Camorra clan had used this kind of technique to dispose of a rival. Galasso claimed that he killed Casillo in order to free DC politician
Antonio Gava and other Christian Democrats from Cutolo's threats. In a meeting held in April 1982, nine months after the kidnapping, Vincenzo Casillo reportedly told Giuliano Granata, the DC mayor who had taken part with him in the negotiations: "You did what you wanted and then washed your hands". According to Galasso, who later became a
pentito, the reasons for his murder were: Although there are some rumors that Cutolo ordered Casillo killed because he had taken Cutolo's part of the Cirillo ransom, Cutolo has stated that he was wary of the untrustworthiness of the politicians and claims to have warned Casillo after the kidnapping: Not long after his death, his partner, the dancer Giovanna Matarazzo, declared to judge
Carlo Alemi that Casillo's death was linked to the murder of Roberto Calvi. Matarazzo disappeared a few weeks after his death, and her body was eventually found in a ditch under a motorway in December 1983. The fact that a secret service card that could be used by Casillo was found in his burnt-out car lends some credibility to the scenario that his death might have been linked to the Cirillo kidnapping. ==Aftermath==
