Five-year-old Isabella de Oliveira Nardoni was killed after she was thrown from the window of her father's sixth floor apartment. Her father, Alexandre Nardoni, told police that Isabella was asleep in her bedroom when he went downstairs to help his wife with the other children. He said that he believed an intruder came in and killed his daughter, but police found no sign of a break-in. Isabella was found badly injured on the grass below the window on March 29, 2008. She died shortly after being found.

Alexandre and wife Anna were arrested and accused of killing Isabella. Blood was found in Isabella's bedroom, and there was a large hole in the safety netting that hung over her window, which convinced police that she was thrown out through it with force.

Neighbors claim that they heard Isabella screaming "Stop, dad!" shortly before she died. After an autopsy, it is believed that Isabella was strangled before she was thrown from the window.
