Roberto Succo (3 April 1962 – 23 May 1988) was an Italian serial killer who committed several murders and other violent crimes mostly in Italy and France in the 1980s.

He hid their bodies in the bathtub covered in water and lime to delay the discovery of the murders and fled with his father's service pistol.

He then fled from Mestre,[1] but an investigation into the murders of the Succo couple immediately connected them to the son, who was arrested two days later at the exit of a pizzeria in San Pietro al Natisone, not far from the border with Yugoslavia, after he had briefly returned to the crime scene.

After Succo was caught, he was judged mentally ill and sentenced to ten years in a psychiatric prison in Reggio Emilia.

French journalist Pascale Froment wrote a non-fiction account of Succo's crimes that appeared as Je te tue.
