Italy has been left in shock after disturbing reports of a murdered family.
A 17-year-old boy is believed to have attacked his family with a knife at their home in Paderno Dugnano, a town to the north of Milan, on the morning of September 1.
The teenager allegedly stabbed his 12-year-old brother with a 20cm kitchen knife, Lorenzo, a total of 10 times, letting out a loud scream that woke his parents in the process.
Oblivious that their eldest son, who was already in the room when they arrived, was the accused killer, dad Fabio Chiarioni called on him to help at which point it is believed the teen tragically launched at him and mother Daniela Albano,
The son then dialled the emergency services for help, AP reports, with him initially claiming to have killed only the father in self-defense and blaming him on the deaths of his mom and brother.

When police arrived at the scene the boy was stood outside in front of his home covered in blood, wearing just his underwear while gripping a knife – which he dropped the moment cops arrived, officials reported.
However, authorities questioned the teen and for hours after taking him in and his story began to unravel, as it was clear he had no injuries that consisted with that of a struggle.
According to local media, the 17-year-old confessed to killing them.
“There is no real reason why I killed them. I felt like a foreign body in my family. Oppressed. I thought that by killing them all I would free myself from this discomfort.”
Most disturbingly, the teen also said he had been listening to music by the Beatles days before, repeatedly listening to one line in particular from the song The Long and Winding Road.

He told the police that he had listened to the lines ‘Many times I’ve been alone/ and And many times I’ve cried’ on repeat.
The allege killer also told police: “I realized it a minute later. I understood that it was not by killing them that I would be freed.
The mayor of the town Anna Varisco spoke about the grim incident and the family: “They were a normal, serene family, not followed by social services and described by everyone as not having problems.”
Police are continuing to investigate the incident.
