On the day of the murder, in July 2014, Romano texted her boyfriend saying she was going to tie him up and that he should be ready for ‘a party’.
But when he was tied up, she stabbed him repeatedly before running away with his cash.
Romano later confessed to having been at the place of the crime but denied taking part in any sex game.
During the trial she said she could not remember what had happened and refused to answer questions.
She told the court: ‘I loved Julio, I do not understand what happened.’
But she was sentenced to life in prison after being found guilty of murder after the court heard she took advantage of the ‘trust’ that Julio had in her.
Crime scene doctors confirmed that the silk ties were not tight enough to completely limit the victim’s movements.
This led investigators to believe that Vittoria entered willingly into a sexual game with someone he trusted, who then took advantage of his vulnerable position.
Court witnesses claim that Romano was ‘addicted to sex’ and in her hospital records she had been diagnosed with a sex-related behaviour disorder.
Doctors said as well as experiencing rage attacks, she had an uncontrollable impulse to be unfaithful and sometimes experienced ‘disgust’ and ‘rejection’ when having sex.
