A Bexar County constable is fighting back against critics who said one of her top deputies should not be on the streets.

"I'm very transparent. I have nothing to hide," said Bexar County Precinct 2 Constable Michelle Barrientes Vela.

Barrientes Vela believes someone is leaking bad information to the public.

"We are looking into the issues concerning classified and sensitive information that was released from our department, which could lead to criminal charges," said Barrientes Vela.

Vela launched an internal investigation after another media outlet obtained classified documents and reported her captain, Anthony Castillo, was not commissioned to work at the constable's office on day one of Vela's term.

Vela said she was even contacted by the Texas Commission on Law Enforcement, or TCOLE.

"I did provide all necessary information pertaining to my captain and did verify that he was licensed and was commissioned by my department. Therefore, they dismissed that call," said Barrientes Vela.

At the advice of an attorney, Castillo, a former Bexar County Sheriff's deputy, won't comment publicly.

A TCOLE representative tells KENS 5 they are unaware of any active investigations that question Castillo's credentials.

Castillo and Vela feel that much of the fuss is from former employees who don't like changes she's made.

"They allowed deputies to take home vehicles, do part time jobs using county vehicles and use county gas money, which to me is stealing and unethical as an officer. This practice was immediately stopped when I took office," said Barrientes Vela.

Constable Barrientes Vela said once her internal investigation is complete, she plans to hand the findings over to the Texas Rangers.
