CORPUS CHRISTI, Texas — A Mathis woman has pleaded guilty to first-degree murder and first-degree injury to a child in connection with the death of her 7-month-old daughter.

According to a Mathis Police Department report, officers were called to a home on Marigold Street around 6:30 a.m. on Dec. 19, 2023, for a report of a 7-month-old who was unresponsive and not breathing. Emergency crews performed CPR before the infant was taken to Northwest Hospital in Calallen, where the child was pronounced dead a short time later.

Investigators attended the baby’s autopsy the next day, which showed multiple injuries, including broken arm and leg bones and a skull fracture, according to the probable cause statement. 

The statement said Munoz later admitted to striking her daughter several times with a closed fist, telling investigators she had hit the baby on the arms, legs and abdomen on at least three separate occasions.

A San Patricio County grand jury later indicted Munoz on charges of capital murder of a child under ten and injury to a child. The case was formally filed with the district court in early 2024, according to court records.

Munoz’s plea agreement calls for life sentences on both counts. A sentencing hearing is scheduled for Nov. 13 in the 36th District Court in Sinton.
