Mr Turetta, 22, can be seen beating his former partner in a car park close to her house in Vigonovo, near Venice - according to the investigating judge.

“He was a normal boy, practically perfect,” his father Nicola Turetta said in an interview with Italian newspaper La Repubblica.

“He did well in school, he never had any problems with teachers or classmates. He never got into arguments with anybody.”

Ms Cecchettin’s sister Elena said she had been concerned about his possessiveness, but never imagined he could hurt her.

She pointed to a patriarchal culture of violence and control over women that normalises men’s dangerous behaviour.

“Filippo is often described as a monster, but he’s not a monster,” Elena told Italian media. "A monster is an exception, a person who’s outside society, a person for whom society doesn’t need to take responsibility.

“Monsters are healthy sons of the patriarchy and rape culture,” she added.

This is the best summary I could come up with:

The killing of a young woman in Italy, allegedly at the hands of her possessive ex-boyfriend, has shocked the country and prompted a reckoning about violence against women.

On 11 November - days before 22-year-old Giulia Cecchettin was due to get her biomedical engineering degree - she went to buy her graduation outfit with her ex-boyfriend Filippo Turetta.

Giulia Cecchettin’s killing has sparked an unprecedented outpouring of grief and anger in Italy, where many women say patriarchal attitudes are entrenched.

Elisa Ercoli, director of Differenza Donna, a non-government organisation fighting gender-based violence, told the BBC that the killing was “the last straw, after a string of high-profile cases of femicides.”

Giorgia Meloni, Italy’s first female prime minister, has expressed outrage at the country’s long history of violence against women by partners and ex-partners.

“And while women have made big steps forward and are much more aware of their rights, men are still firmly anchored to the idea of a patriarchal relationship,” Ms Ercoli says.
