Overview
- Denise Cosco jumped from a window on Sunday, September 6, and died on September 10 at age 35 after four days in hospital.
- The Procura di Velletri opened an investigation for istigazione al suicidio against unknown persons, ordered an autopsy, and seized Cosco’s cellphone for forensic analysis.
- Denise was a longtime testimone di giustizia who testified against her father, Carlo Cosco, in the trial over the 2009 murder of her mother, Lea Garofalo.
- She lived under the national witness protection programme until 2018, adopted a new identity, and left behind a young son reported to be about four years old.
- Civil‑society leaders including Don Luigi Ciotti framed her death as the human cost of mafia violence and the long strains of protection, a development that could renew scrutiny of long‑term support for collaborators.
