Denise Cosco, daughter of anti mafia witness Lea Garofalo, dies aged 35

Rome — Denise Cosco, the daughter of murdered anti mafia witness Lea Garofalo and one of Italy’s most powerful symbols of resistance to the ’Ndrangheta, has died aged 35 after taking her own life in Rome.

According to Italian authorities, Denise jumped from a window on Sept. 6 and died four days later in hospital following critical injuries. Her death has prompted renewed reflection on the lasting psychological burden carried by victims’ families and those who lived for years under witness protection.

Denise was only 19 when she became a key witness in the trial over her mother’s murder. Hidden behind a screen in court, she gave evidence against her own father, Carlo Cosco, the ’Ndrangheta affiliate who was later sentenced to life imprisonment as the instigator of the killing.

During the proceedings she described her mother’s isolation and despair, telling judges that Lea felt abandoned and unprotected despite cooperating with investigators. Explaining why she initially remained with her father after her mother disappeared, Denise said she feared suffering the same fate as Lea while secretly knowing the truth.

She later declared herself “a proud witness for justice,” calling her decision to testify against her father “a choice of inner freedom.”

After the trial Denise lived for years under a new identity in a secret location as part of Italy’s witness protection programme. The protection measures ended in 2018, after which she settled in Ariccia, near Rome, with her partner and their young son, who is now almost four years old. She was employed at a ministry in the capital.

Friends described her as a deeply troubled woman who never succeeded in healing the wounds left by the murder of her mother and the imprisonment of her father.

Lea Garofalo, born in Petilia Policastro in Calabria, became a witness for justice in 2002 after exposing violent feuds within the ’Ndrangheta involving her own family and that of her former partner. Her testimony led to major investigations into organised crime.

In November 2009 she was lured to Milan by Carlo Cosco under the pretence of discussing their daughter’s future. She was abducted, tortured and strangled before her body was dismembered and burned. Her remains were discovered in Monza in 2012 after information provided by a collaborator with justice.

The murder shocked Italy and transformed Lea into a national emblem of the fight against organised crime. At her public funeral in 2013, Denise wrote that her mother had possessed “the courage to rebel against the culture of the mafia” and had defended dignity and justice until the end.

Luigi Ciotti, founder of the anti mafia organisation Libera, paid an emotional tribute to Denise, describing her as “a courageous and suffering young woman” who had spent her life trying to balance those two forces.

“She dreamed of finally feeling free and independent,” Ciotti said. “Like Lea, Denise had a great thirst for life, freedom and love.”

He urged the public not to judge or romanticise her story, saying her memory should instead strengthen the collective commitment to justice and support for those who bear the consequences of organised crime.
