[5] Prosecutor François Molins said the attacker, Larossi Abballa, appeared to be acting on a recent general order from Abu Bakr al-Baghdadi to "kill miscreants at home with their families" during the month of Ramadan.
[citation needed] Abballa finally caught up with the police officer, stabbing him again several times before barricading himself in the house of his victim.
Inside the house, he murdered the victim's partner, Jessica Schneider, a 36-year-old administration worker at the Mantes-la-Jolie police station, by slitting her throat.
[10] Inside the house, at 8:52 p.m., Abballa started a Facebook Live broadcast on his mobile phone while the RAID and BRI police special forces converged on the crime scene and set up an attack plan.
In his 13-minute-long live broadcast, Abballa claimed his double murder and his allegiance to Abu Mohammad al-Adnani, ISIL's spokesperson, considered as the leader of the November 2015 Paris attacks.
The New York Times reported that "Abballa's Facebook post from Monday night made clear that he wanted to terrify and destroy those he deemed 'unbelievers', people he had come to hate.
During these negotiations, Abballa said he was a practicing Muslim, that he was observing Ramadan, and that he swore allegiance three weeks earlier to ISIL leader Abu Bakr Al-Baghdadi.
[16][17] In that year, Abballa, then age 20, was arrested for his participation in a group that recruited would-be jihadis to go to Pakistan and Afghanistan for training.
