DEL RIO, Texas -

A Maverick County commissioner surrendered to federal authorities Thursday morning, after a federal grand jury indicted him on bribery and fraud charges.

The indictment, returned Wednesday, charges Precinct 1 Commissioner Eliaz Maldonado, 52, of Eagle Pass, with four counts of wire fraud and two counts of receiving bribes.

The indictment alleges that in 2010 and 2011, Maldonado rigged the bidding process to guarantee that the contractors he chose would be awarded Maverick County construction contracts.

According to the indictment, the private contractors submitted inflated bids to Maverick County in order for there to be sufficient funds to perform the construction work, make a profit, and pay a bribe to Maldonado.

If convicted, Maldonado faces up to 20 years in federal prison for each wire fraud charge and up to 10 years in federal prison for each bribery charge.

Maldonado is the second Maverick County commissioner to face federal charges since October, when Commissioner Rodolfo Heredia and two accomplices were charged in connection with a money laundering and bulk cash smuggling scheme.
