Growing suspicion – Experts have used cellular tracking technology to determine that a laptop belonging to Abdelkader Merah, the brother of Toulouse gunman Mohamed Merah, was located near the Jewish school where the latter shot dead four people on Monday. The computer appeared to have been near the scene of the shooting on the day of the attack.
Abdelkader, who has been taken in for questioning in Paris, denied involvement in his brother's shooting spree.

"She is devastated," he told reporters after her release. "At no time could she have imagined that her son was the one who did it."
Aziri was freed late Friday from a police station in Toulouse, a judicial official said on condition of anonymity because the information wasn't cleared for public release.
Police have found explosives in a car Abdelkader owned, according to the public prosecutor leading the case. He was already known to security services for having helped smuggle jihadist militants into Iraq in 2007.
A police source said on Saturday that at a closed hearing in Toulouse he had declared himself "proud" of his brother's killings and had admitted helping Mohamed steal the scooter used in all seven murders. He had denied any knowledge of his brother's murderous plans, however, the source added.
