SAN ANTONIO -- A 2-year-old boy escaped serious injuries Sunday night when the impact from a car that hit his grandmother who was carrying him sent him rolling into the vehicle's sunroof and landing safely inside the vehicle, police said.

The 45-year-old woman was carrying her grandson in her arms as she attempted to cross the intersection of Bynum and King avenues and a car struck her, police said.

The impact sent the woman crashing to the ground, police said. Her grandson flew from her arms and smashed into the car's windshield. The toddler then rolled up the windshield and through an open sunroof and landed safely on the car's passenger seat, police said.

The toddler appeared to only have suffered minor injuries.

The toddler's grandmother was transported to University Hospital in critical condition, although police said it appeared she would make a full recovery.

The driver of the car, Reece Barcenes, said the only reason the sunroof was open was that the sun was shining brightly hours earlier.

"I didn't close it for whatever reason," he said. "And I just happened to have it opened. Everybody here tells me it was an act of God that I had it open. Had it been not been open or a hard top, God knows what would have happened to that baby."

Police are handling the incident as an accident and don't plan to charge Barcenes.
