A 55-year-old woman, an elementary school teacher, found dead in her home in Bagheria, in the Palermo area, would have been strangled by her 17-year-old daughter.
The minor is in custody for voluntary homicide.
The provision was issued by the prosecutor for minors, Claudia Caramanna, at the end of the long interrogation.
The 17-year-old confessed to the crime.
According to what emerged from the investigations, there had been constant quarrels between mother and daughter for some time.
The quarrel between the primary school teacher and her minor daughter would have broken out at three last night.
It was the seventeen year old, this morning around 8, who sounded the alarm.
The woman taught in an elementary school in the province of Palermo.
According to what has been learned, the girl at first would have told rescuers about suicide.
But her reconstruction of her facts collapsed during the interrogation before the prosecutor for minors of Palermo, Claudia Caramanna.
According to a first investigative hypothesis, the woman would have been strangled.
