Denise Cosco was found critically injured on Sunday and later died in hospital, the same age her mother had been murder‑shot.
Denise’s mother, Lea Garofalo, was murdered in 2009 by the 'Ndrangheta clan. Garofalo’s courage as a state witness turned her into a powerful symbol of resistance to the mafia. Denise followed in her mother’s footsteps, testifying against her own father, Carlo Cosco, who was convicted for the killing.
Friends of Denise recount how she switched identities, lived under a new name for years, but later re‑connected with her father in prison, illustrating the complex ties of family and organised crime. They also recall her ongoing battle with mental‑health issues and addiction.
Anti‑mafia lawyer Enza Rando called the death a “profound wound for the entire country” and said the mafia “creates true monsters in the lives and souls” of survivors. Francesca Rispoli of Libera highlighted that the mafia’s influence extends beyond physical violence – family anchors remain deep and difficult to unmake.
Investigators are now probing whether there was any incitement to suicide. Denise’s phone has been seized for analysis. Friends planned a remembrance in Milan near the site where she was abducted in 2009.
