Evidence has emerged that the man who killed four people inside Paris' police headquarters on Thursday (October 3) showed signs of religious "radicalization." That's according to French anti-terrorism prosecutors on Saturday (October 5).
It includes, they say, 33 text messages between the 45-year-old IT worker and his wife ahead of the knife rampage.
All of them were of a religious nature.
It also includes comments made to a coworker attempting to justify the militant Islamist massacre at the Charlie Hebdo newspaper in 2015.
It had been previously reported that the killer was a convert to Islam but prosecutors say that he converted about 10 years ago.
If he was radicalized, it's not clear how or when it would have happened.
Police also declined to say if religion played a role in the actual motive for the killing.
Officials have said there were no previous causes for concern about the employee.
And shortly after the attack French media, citing police sources, said the attacker had a grievance with his managers.
Three police officers and an administrative worker were killed before he was fatally shot.
