HIGH RIDGE, Mo. - It's a story of a young life saving an even younger one.
When an 11-month-old stopped breathing inside the High Ridge Walmart store Wednesday, Hillsboro High School student Abby Snodgrass knew exactly what to do.
"I was in the dressing room and I heard them call for the emergency over the radio," Snodgrass said. "They said, 'No pulse, no breathing.' And I just ran over there."
Snodgrass found a crowd surrounding the infant and her panicked mother.
"She did not look like a normal baby, she didn't look alive. And once I saw that no one was doing anything I asked if anyone knew CPR."
It turns out Snodgrass had recently learned CPR at her school.
"It was just a couple months ago in my health class."
"In the fall of 2013, we started teaching every semester all the high school kids in the Hillsboro school district CPR," Valle Ambulance District Chief Jesse Barton said. "By the end of this year we will have taught around it to around 600 kids."
Snodgrass says the test at Walmart was greater than any she's faced in the classroom.
"I was terrified. I remember thinking as I'm doing the compressions, what if this doesn't work? But I had to put it out of my mind," said Snodgrass.
The young lady is a remarkable individual," Chief Mike Arnhart, of the High Ridge Fire District, said.
He responded to the 911 call and says had it not been for Snodgrass' bravery, the infant may not have survived.
"Seconds count," Arnhart said. "In this case this young lady stepped up, her training kicked in and she did exactly what she was trained to do."
Snodgrass' Family and Consumer Sciences teacher says the young woman is a perfect example for her fellow students.
"She's an awesome kid and I'm overwhelmed and excited for her," said Erica Huskey. "Now I think (the other kids) are all thinking, 'Wow, what if we have to use this too?'"
Snodgrass says the experience may help her in the next phase of her life as she's already enlisted in the National Guard.
She says her biggest regret is not being able to spend time with the infant's family after things calmed down. She's hoping to re-connect with them just to make sure everything is okay.
