PARIS (AP) — French officials still aren’t sure exactly how Abdelhamid Abaaoud died.

They’re confirming that he died yesterday along with his female cousin in a police raid on an apartment building in suburban Paris.

He was the suspected mastermind of last week’s deadly attacks. Authorities haven’t spelled out his exact whereabouts or his actions during the deadly rampage.

Three police officials say a woman killed during a raid on an apartment in suburban Paris was his cousin. One official says Hasna Aitboulahcen is believed to have detonated a suicide vest after a brief exchange with police officers.

According to the official, one of the officers asked: “Where is your boyfriend?” and she responded angrily: “He’s not my boyfriend!” Then there was an explosion.

The bodies recovered in the raid were badly mangled, with a part of the woman’s spine landing on a police car, complicating formal identification.
