A similar incident happened about the same time in Fishers, Ind., where a passerby at a shopping center noticed a small girl alone in a parked Ford Explorer.
Police broke out a window to pull the 16-month-old girl from the SUV. She suffered a seizure before medics transported her to Peyton Manning Children's Hospital in Indianapolis, said Fishers Police Public Information Officer Tom Weger.
Officials said the temperature inside the car after the window was broken was 124 degrees.
The child's mother, Meg Trueblood, 30, of Fishers, was shopping in the Simply Chic clothing store at the center for about an hour while her daughter was left in the locked SUV, Weger said.
Trueblood was preliminarily charged with felony neglect of a child and was being held in the Hamilton County Jail, Weger said. He said Trueblood made a statement to police but, "she didn't appear to be fully coherent. That'll be part of the investigation."
The high temperature in Indianapolis on Saturday was 105 degrees, which broke the previous record for the day of 101 set in 1936. Tips on avoiding a tragedy
Never leave kids alone in a hot car, even briefly.
Always check the front and back seats of the car before you lock it and leave.
See a kid alone in a hot car? Call 911 immediately. Get them out ASAP if they are in distress.
Put your purse, briefcase, or something else you need by the car seat so you don't forget to check.
Always lock your car when it's empty so kids can't get in without you knowing.
