In 1982, Gioeli allegedly participated in the accidental killing of Veronica Zuraw, a former Catholic
nun. Zuraw was killed by a stray bullet during the assassination of Colombo mobster Joseph Peraino. Government witness Dino Calabro claimed that Gioeli told him he was "going to hell" for killing a
nun. However, Gioeli maintains his innocence and no charges in the Zuraw killing have been filed against him. In 1997, Gioeli allegedly participated in the murder of Ralph Dols, a
New York Police Department (NYPD) officer. Colombo consigliere
Joel Cacace had ordered Dols' death because Dols had recently married Cacace's ex-wife, Kim Kennaugh. Gioeli allegedly took the order from Cacace and arranged for Calabro and Colombo mobster
Dino Saracino to shoot Dols outside his Brooklyn house. In 1989, the imprisoned Colombo boss
Carmine Persico appointed Orena to be his temporary acting boss. By 1991 Orena, with the encouragement of
Gambino crime family boss
John Gotti, felt strong enough to challenge Persico for total control of the family. In response, Persico tried to assassinate Orena in 1991. This attack triggered a bloody internal conflict in the Colombo family between the Persico and Orena factions. Gioeli gave his support to Orena. Bloody shootouts between the two factions in 1991 resulted in murders of prominent Orena supporters. As the war progressed, many Orena loyalist switched sides to the Persico faction to avoid being killed. In 1991, Gioeli switched sides and became the top lieutenant and protégée of hitman
Gregory Scarpa Sr. On June 12, 1991, Gioeli, Calabro, and soldier
Joseph Competiello allegedly murdered Frank Marasa, an Orena loyalist, outside Marasa's home in
Brooklyn. Gioeli allegedly murdered Marasa because he was falsely accused of being involved in the murder of another Colombo associate. == Fall of Orena and victory ==
