Denise Cosco, who helped expose her father's mafia crimes, died by suicide after years of protection and mental struggle.

Denise Cosco, a key witness who testified against her mafioso father, was found dead after a serious injury. Her mother’s murder in 2009 made them both symbols of resistance. The men's ties to the ‘Ndrangheta left Denise deeply vulnerable, leading to mental health issues and addiction. Anti‑mafia groups say the case shows the need for lifelong support. If you’re dealing with despair, help is available.

Denise Cosco, witness against her father, took her own life after years of protection and mental struggle.

Denise was found critically injured on Sunday and died in hospital. She had been a pivotal figure in exposing her mafioso father’s crime for her mother’s murder in 2009.

Lea Garofalo’s death, with the body dismembered and incinerated, turned her into a symbol for fighting organised crime. Denise’s brave testimony at the trial left her life torn between courage and suffering.

The mafia’s grip goes beyond physical violence. Family ties can be hard to erase, and anti‑mafia lawyers say more long‑term care is required for people turned from crime.

Friends report Denise struggled with mental health and addiction, and that she reconnected with her father in prison to fill a painful void.
