The grim discovery of a pair of sawn off legs was made in the Parioli neighbourhood in the north of the capital on Tuesday, August 16, by a young woman believed to have been searching through the bins.
Police investigations have since ascertained that that the victim, 59-year-old Nicoletta Diotallevi, was strangled and then cut up with an ax by her 62-year old brother Maurizio, who has confessed to the crime, according to Il Messaggero.
The same daily reports that the man was seen leaving his home, which he shared with the victim, at around 1.30am on August 16.
Maurizio Diotallevi, the victim's 62-year-old brother, had been planning the murder for two months because his “sister always humiliated” him, according to a report by Italian national news agency Ansa. Diotallevi confessed to strangling his sister in their flat then chopping her to pieces.
The autopsy confirmed that the cause of death was strangulation.
According to a police spokesperson cited in Repubblica, the legs had likely been sawn off and dumped in the refuse container the previous night, “judging from the initial state of decomposition”.
Forensic experts found the other missing body body parts belonging to the victim near where the legs were found on the morning of August 16.
The victim's body parts were allegedly hacked to bits with an ax at her home before being dumped in the rubbish container, according to the same report in Il Messaggero.
The victim's brother was seen walking away from the bin on Monday night, when the legs were dumped according to forensic analysis, but it took investigators an extra 24 hour to confirm the man's guilt.
Several reports in Italian dailies claim money issues between the siblings could have been the motive behind the grotesque sororicide.
In 2015, Rome was shaken when a severed leg tattooed with the words “Today is a good day to die” was fished out of a tributary of the River Tiber, which flows through Rome, according to AFP.
That leg, which had been severed above the knee, belonged to a hardcore fan of the Rome football club Lazio who was a known drug user and had a criminal record.
