Commissioner of the Judicial police of Palermo, he was chief of the newly created Sezione Catturandi, which was responsible for the search for fugitives.
In this role he gained great results, discovering Michele Greco's arsenal in 1983 and capturing Tommaso Spadaro (Giovanni Falcone's childhood friend), who became the boss of cigarette smuggling and drug trafficking.
He continued to work closely with the pool until his last day, consolidating the relationship with that structure born with prosecutor Rocco Chinnici, engaged in the front line of the struggle against the Cosa Nostra.
"[1] Three days before the death of Montana, on July 25, 1985, his team had arrested eight men of Michele Greco, who managed to escape from capture.
On July 28, 1985,[2] the day before going on holiday, Montana was killed by three Corleonesi hitmen, armed with revolvers (a 357 Magnum and two .38 Special with expanding bullets), while he was with his girlfriend in Porticello, a fraction of Santa Flavia[3] near the harbour where his motorboat was moored.
