The hostage-taker, who gunned down a police officer before shooting dead four people in a Paris supermarket last week, assembled his cache of deadly weapons at a hideout in the Parisian suburb of Gentilly, along with the black flags of ISIS, ammunition, and several IDs.

The militant Islamist's final hide-out was raised by police last Saturday and investigators are now hunting a fourth 'accomplice' whose traces were found at the second floor apartment.

Coulibaly was married to Hayat Boumeddiene, another 26-year-old Islamic fanatic, who is thought to have helped mastermind the bloody slaughter which left 20 dead, including the three terrorists, around Paris last week. She then fled to Syria

The Islamic fundamentalist disowned his own parents as far back as 2010 as he begun a spiralling descent into radical Islam, police wiretaps reveal.

The French Muslim was arrested in May of that year for his part in a plot to free a convicted terrorist from prison.

Prosecution documents obtained by MailOnline, show that even then Coulibaly had turned his back on his family because of ‘their kaffir ways’.

'Kaffirs' are Muslims who are regarded as having rejected the Qaran.

The documents also suggest that the Muslim of Malian origin may have already been flirting with the idea of martyrdom, as he was recordeded asking what would happen to his debts when he died.

And a psychiatric evaluation at the time revealed that the future killer even then had ‘psychopathic tendencies.’

Interviews with his terror-fixer wife Hayat Boumedienne, published earlier this week, revealed that Coulibaly was already making frequent visits to a suspected terror training camp in France.

The alleged camp, where Boumedienne was photographed firing a crossbow in full burkha, was run by Djamel Beghal alias Abou Hamza, himself a disciple of reviled London hate preacher Abu Hamza.

The cache of new documents record how Coulibaly boasted to his mentor that he had fully rejected his family in favour of a complete devotion to militant Islam.

In police wire taps, the French Muslim, a trained electronic audio visual installer, related how he had ‘disowned his parents’ whom he was disgusted with because of their more relaxed interpretation of their faith.

In the interceptions Coulibaly relayed to Hamza how he flew into a furious rage with his sisters when they asked him for help with their children because he did not believe that they were being raised as proper Muslims.
