The baby's mother, Vibha Marks, was arrested. Police said she is a teacher at the school.
Dallas police Lt. Paul Stokes said a witness noticed the infant inside the locked vehicle at about 1 p.m. It was about 86 degrees outside.
Exenia Gomez, who saw the child, smashed the window with a 2x4 she had in her truck. Stokes said Gomez performed CPR until EMTs arrived to take the baby to Baylor Hospital, where she was pronounced dead.
"I just came out of my truck and I see something pink and I see there is a baby in there," Gomez said. "I looked straight at the baby and it wasn't moving or anything."
The baby was identified as Victoria Marks. She had her first birthday on Thursday.
"I actually held her and saw her face," Gomez said. "Unimaginable."
Gomez is an intern at the school. She said baby Victoria was wearing shorts and a pink top and was still strapped to her carseat.
Vibha Marks, 42, was arrested after being interviewed at Jack Evans Police Headquarters. She was charged with child abandonment and freed after posting $50,000 bond.
A statement from the Dallas Independent School District said the teacher was placed on administrative leave pending a police investigation. The district sent home a letter to parents and said grief counselors are on hand for anyone who needs them.
"Obviously this is a very tragic situation," the district's statement reads. "Our thoughts and prayers are with the teacher and her family at this time, as well as the staff at Guzick Elementary."
