In his complaint, De La Garza alleges Bowman tampered with local government by trying to influence Goliad ISD officials to not hire Paul San Miguel as the school district's school resource officer.
The commission would not release any information on the complaint or investigation to the Advance-Guard on Friday. De La Garza said he could not provide the complaint to the Advance-Guard for fear of hampering the investigation.
De La Garza said he filed the complaint in May after the Goliad County Commissioners Court voted to terminate the interlocal agreement with Goliad ISD to provide an SRO for the school district. Bowman voted to terminate the contract along with Precinct 3 Commissioner Ronald Bailey and Precinct 4 Commissioner Ted Long.
De La Garza said he received a confirmation letter of the pending investigation from the commission in September.
"They let me know that they've started the investigation," De La Garza said.
Bowman did not return phone calls from the Advance-Guard on Friday.
De La Garza said he contacted the commission Friday and was told the investigation was still active.
"They are in the early stages of the process," De La Garza said Friday. "They are reviewing the complaint right now."
Section 151.004 of the local government codes states the "commissioners court or a member of the court may not attempt to influence the appointment of any person to an employee position authorized by the court."
"He violated a Texas local government code where commissioners court may not interfere with an appointment," De La Garza said. "That's why I filed the complaint. It should stick."
De La Garza and his brother, former Goliad County Sheriff and current Goliad ISD Board Trustee Robert De La Garza, have claimed openly that Bowman and Goliad County Sheriff Kirby Brumby visited with Goliad ISD officials concerning the employment of San Miguel, who ran against Brumby in the 2012 sheriff's election.
Last week, Robert De La Garza had his lawsuit against Brumby settled out of court. Robert De La Garza claimed in his lawsuit that Brumby prevented him from being hired as the Goliad ISD SRO.
