The death of Isabella Nardoni in 2008 shocked Brazil, and the case has been the focus of intense media coverage.

Her father, Alexandre Nardoni, was sentenced to 31 years in prison by the São Paulo court. Her stepmother, Anna Carolina Jatoba, must serve 26 years.

The couple, who had denied the girl’s murder, will appeal, their lawyers say. Isabella was found in the communal garden below the apartment where Nardoni, his second wife and their two children lived in March 2008.

Nardoni, a lawyer, claimed that his daughter had been killed by an intruder while he was helping his wife bring the other children form their car, parked in a garage in the building’s basement.

But prosecutors argued that his wife had attacked Isabella in the car and then strangled her in the apartment.
