Two former Fort Stockton police officers have been indicted after one allegedly struck their own child repeatedly with a belt.

Evanjelina Salamanca, 34, has been charged with Injury to a Child and assault causing bodily injury.

Derek Calderon, 21, has been charged with Injury to a Child for failure to prevent actions to protect a child from injury.

The two were dating and working as officers with the Fort Stockton Police Department when the alleged assault happened, according to Pecos County District Attorney Sandy Wilson.

According to the indictments, Salamanca allegedly hit her own child repeatedly with a belt while Calderon did nothing to stop it in the month of March.

Salamanca and Calderon were off-duty at the time of the assault.

On June 6 both Salamanca and Calderon resigned after being indicted.

Both were booked into jail and bonded out the same day.

CBS 7 News paid the couple a visit at their home to get their side of the story, but Calderon's grandmother was the one who answered the door.

“I don't know nothing sweetie, I just got here and I just came to pick up something, I'm on my way home,” said Calderon’s grandmother.

We asked Calderon’s grandmother what she thought about the charges against her grandson and his girlfriend, but she said she didn’t know anything and closed the door on us.

According to investigators there are open cases involving four of Salamanca’s five children.

In addition to Salamanca’s indictment, she's been charged with assault family violence for allegedly hitting her child who's over the age of 14 and charges are pending for the last two.

Calderon is not the father of the four victims, however he and Salamanca have an infant child together, who is not under investigation.

Very few details in this case are available at this time since it is an open investigation, but we will continue to follow it closely.

Wilson tells CBS 7 that the investigation is ongoing and that the Texas Rangers are investigating.
