According to Cameron County Sheriff Omar Lucio, the abuse began when the girl was 11 years old and continued for a span of three years before she recently cried for help.
On Dec. 20, the Children’s Advocacy Group reported the alleged sexual assault to sheriff’s investigators.
Reymunda Hernandez, 45, has been charged with failure to report sexual abuse and three counts of aggravated sexual abuse.
Her bond was set at $305,000 and she faces up to 20 years in prison and up to a $10,000 fine.
Authorities said they are still looking for the man, Jorge Tamez, 41.
Police urge anyone with information that will help locate him to contact local authorities.
Authorities said the assault occurred on Rancho Grande Street in San Benito.
Investigators said Hernandez admitted to forcing the child to take off her clothing and allowing Tamez to sexually assault the girl.
Lucio said the last assault may have been in 2016.
The relationship between Hernandez and Tamez was not clear.
The child is currently under the protective custody of the state.
“It is really unfortunate,” Lucio said. “An experience like this can ruin a person’s life.”
He said children have to know the authorities are here to help.
“They should not keep it to themselves,” Lucio said about child sexual assaults.
Anyone who knows where Tamez may be is urged to contact the local police department or the sheriff’s office at (956) 350-5551.
