"I just can't believe anybody would do that to a child. I think it's deplorable," said Mike Hull.
Hull is a parent and grandparent. He says the thought of leaving a child behind in the back seat of a car is hard to fathom.
"We have two daughters and six grandchildren and I wouldn't leave them for a second," Hull said.
Just last month, a 10-month-old foster child died in Wichita, Kansas after she was left in a hot car for more than two hours in 90 degree weather.
"It can happen. It does happen. We don't want this to happen to you," said Sue Lober with the St. Joseph Safety Council.
The St. Joseph Safety Council has joined other agencies for a social media campaign to spread the word about this dangerous and sometimes deadly mistake.
"The overall goal is to just get that information out there and get people started talking and realizing that they need to make a plan and that this could happen to them," Lober said.
The message of the campaign is simple; these deaths are preventable.
"You know, even if they think they're going to run into the store for a minute or two, you never know what's going to happen," said Hull.
Already this year 19 children have died in hot cars.
The campaign, "Where's Baby? Look Before You Lock," comes on National Heatstroke Prevention Day.
