PLANO, Texas (AP) -

A former employee of a North Texas school district has admitted to bilking the district for at least $2.5 million in an embezzlement scheme.

Prosecutors say Kris Wilson Gentz approved invoices as a security manager for the Plano Independent School District for safety checks that were never actually done. Instead, money from the invoices went to two shell companies Gentz partially controlled for almost a decade.

Gentz pleaded guilty Wednesday to his role in the conspiracy.

John Malcolm Bales, the U.S. attorney for Texas' eastern district, said Gentz appeared to have spent most of his share of the money on weekend trips to casinos in Louisiana.

Bales said it appeared no schools or students were in danger due to fire safety checks not being done.
