A federal grand jury has returned a 37-count indictment charging a Beaumont electrical contractor with federal violations.

50 year old Calvin Walker, owner of Walker's Electric, was indicted by a federal grand jury on May 4th and charged with 3 counts of mail fraud, 6 counts of wire fraud, 5 counts of interstate transfer of funds by fraud, 18 counts of fraud in connection with organizations which receive federal funds, and 5 counts of money laundering involving transactions greater than $10,000.

Toay, U.S. Attorney John Bales announced the federal charges against Walker, related to what authorities call "a pattern of deliberate overbilling" on electrical projects performed by Walker.

His company, "Walker's Electric" is the outside electrical contractor for the Beaumont ISD.

The indictment alleges that from 2008 to 2010, on at least 13 different electrical projects, Walker submitted 16 invoices containing inflated amounts of the costs of materials used in the projects totaling over $3 million.

The indictment alleges Walker misrepresented the material costs and 10% mark-up by over $1.5 million on work performed at the temporary campuses of Regina Howell and South Park.

The indictment also alleges Walker billed BISD for bucket truck rentals of over $600 thousand when his company already owned the trucks and did not have rental costs.

12 News HD stopped by Walker's business and home for comment, but we weren't able to find him at either location.

If convicted, Walker faces up to 20 years in federal prison for each of the wire and mail fraud violations and up to 10 years for each of the interstate transfer, fraud in connection with federally funded organizations and money laundering violations.

12 News HD spoke with Walker's attorney Dick Deguerin by phone. Deguerin said, "I'm angry because we've been led to believe that we would have an opportunity to present to the grand jury...but we were denied."

A court date for Walker is currently pending.

Davilyn Walston, with the U.S. Attorney's Office says they waited to unseal the indictment to make sure elections would not be affected by the grand jury's decision.

BISD attorney Melody Chappell says the school board will discuss what to do about current contracts with Walker.
