Oksana Martseniuk, 38, was murdered by 35-year-old Federico Leonelli at a gated property in Rome on August 26th. He was then shot and killed by police at the scene.
Investigators have now traced through 40GB of footage from security cameras in the home, in Rome’s Eur neighbourhood, and have pieced together the events which led to the murder.
The evidence suggests that Leonelli killed Martseniuk after a sudden outburst and did not plan the murder, La Repubblica reported.
Footage shows the killer in the basement laundry room, cutting clothes and cloth into pieces with a large knife. The maid then walks in and, seeing the house guest holding the blade, runs away.
Leonelli is shown chasing Martseniuk and stabs her repeatedly; part of the attack has been captured by a security camera looking into the house from the garden.
A vital part of the investigation centres on the death of the killer, as police earlier said that he was shot after attacking officers. Video footage backs up this claim, showing the police and fire brigade arriving and following a trail of blood to Leonelli’s room in an outhouse.
The killer had dragged his victim’s lifeless body into his room where he decapitated her, La Repubblica said. CCTV shows officers approach the outhouse and Leonelli come out and attack them, before being shot.
In an interview given to the newspaper last month, homeowner Giovanni Ciallella said he had allowed Leonelli, a former colleague, to stay in his house over the summer.
Ciallella however noticed his guest’s increasingly strange behaviour, including playing with knives in the garden and saying he wanted to fight alongside the Israeli army in Gaza.
The night before the murder Martseniuk sent Ciallella a text message saying she was scared of Leonelli, although the homeowner said he did not read it until it was too late.
