A Texas mother was taken into custody Tuesday after police alleged her 22-month-old child died when she left the infant in a car outside a Corpus Christi school on one of the hottest days of the year.

The mother, 33-year-old Hilda Ann Adame, was jailed on charges of causing serious bodily injury to a child and child endangerment/abandonment with imminent bodily injury, according to a Corpus Christi Police Department incident report.

It was not clear how long the infant had been in the car before the baby was found unresponsive, according to the incident report.
