The Murder of Marco Vannini

Marco Vannini was a young man from Cerveteri. On the evening of May 17, 2015, he was at the Ladispoli home of his girlfriend, Martina Ciontoli, and her family. During the evening a firearm held by Martina's father, Antonio Ciontoli, discharged and struck Marco. The long criminal case that followed focused heavily on what the people in the house did after the shot and on the delay before Marco received effective emergency care.

The emergency calls

Emergency-service recordings became central evidence. A first request for an ambulance was cancelled, and later information supplied to emergency operators did not accurately communicate the seriousness of Marco's condition or the fact that he had been shot.

The courts ultimately concluded that the conduct after the shooting was not a simple mistake about a minor injury. The legal findings distinguished Antonio Ciontoli's responsibility from that of his wife, Maria Pezzillo, and their children Martina and Federico.

The shooting was not treated as a deliberate firing

The final judgment did not rest on a finding that Antonio intentionally fired at Marco. Instead, his final conviction for intentional homicide with dolo eventuale concerned the conduct that followed: the appellate court found that, after the accidental gunshot, he understood the serious risk to Marco's life and nevertheless accepted that risk while delaying and misleading the effort to obtain appropriate help.

That distinction is essential. Describing the gunshot itself as a planned or intentional shooting would overstate the judicial findings.

A long appellate history

The case moved through multiple levels of the Italian courts. Earlier judgments changed the legal characterization and the sentences, including an appellate reduction that treated Antonio's conduct less severely. Italy's Court of Cassation then ordered a new appellate review.

At the second appeal, on September 30, 2020, Antonio Ciontoli received 14 years in prison for intentional homicide with eventual intent. Maria Pezzillo, Martina Ciontoli and Federico Ciontoli each received 9 years and four months for the form of participation described in Italian law as concorso anomalo.

The final Court of Cassation ruling

On May 3, 2021, the Court of Cassation rejected the defense appeals and made those sentences definitive: 14 years for Antonio and 9 years and four months each for Maria, Martina and Federico. The four then entered custody to serve the sentences.

The final judgment is why this file classifies the case as solved and adjudicated. The page does not merge the four roles into one: Antonio's conviction and the three relatives' convictions rested on different legal forms of responsibility.

Later sentence administration

Sentence administration can change without changing the conviction itself. In January 2025, Martina Ciontoli was authorized to work outside prison during the day and return to custody afterward. Italian reporting described this as a work-release measure granted during execution of her 9-year-and-four-month sentence.

That permission did not overturn the conviction or reduce the final sentence imposed by the Court of Cassation. The other convicted family members were still reported in custody in the same update.
