MEXICO CITY (AP) -- Mexican authorities have arrested and frozen the bank accounts of the grandfather and father of the 11-year old boy who killed his teacher and himself in a northern city last week.

Prosecutors in the border state of Coahuila say the boy used two pistols that belonged to his grandfather, with whom he lived.

The grandfather had the unregistered guns at home and faces a charge equivalent to negligent manslaughter, but prosecutors added Wednesday that questions have arisen about unusual financial transactions by the grandfather and father.

Chief financial investigator Santiago Nieto says "the financial irregularities concern income from possible money laundering and tax evasion."
