With Mohamed Merah now buried in Toulouse, French authorities are now turning their attention to the investigation.
Merah's brother has been handed preliminary charges of alleged complicity in preparing the killings, though his lawyer insists he is innocent.
Abdelkader Merah told investigators that a third man helped the brothers steal a motorbike used later in the killings, two police officials said today.
Merah did not give the name of the other man.
