The Butler County Sheriff's Office continues to investigate after a three-month-old girl died in a car this weekend.

"It is a tragedy," said Herzet. "A three-month-old child dying, whether it be in the hands of a perpetrator or in a car, is still a child."

A 44-year-old mother called for help on Saturday around 4:30 p.m. to her home near 160th Street and Meadowlark Road, in a rural area outside of Rose Hill. 

The child was found not breathing and died at the scene.

Investigators learned that the mother had returned home from a baby shower around 12:30 p.m. and left the child in the car.

"She had commented that she had been very tired. She'd been up some of the night before off and on. Don't know if it was with children or for what reason, but she felt like she needed a nap. She laid down about 12:30 p.m. and slept 'til about 4 o'clock," he said.

Herzet said the couple had six children, five of whom were adopted, ranging in age from three-months-old to 13-years-old.

"It seems like a very good family, very well-natured, took very good care of their children. Like I said, it's been a very tragic event that's occurred there," said Herzet.

An autopsy is being conducted to determine the cause of death. The infant's name has not been released.  

The non-profit is encouraging parents to place a purse or phone in the back seat to remind you to open the back door. Another idea is to place a stuffed animal in the front passenger seat to remind you that a child is in the back seat. For more tips, click here.

This is the 11th child who has died in a car this year. Last year, there were 52.
