A 7-year-old South Carolina boy was hailed as a hero after he saved his diabetic father, who had fallen unconscious, by jumping on his bike and looking for help.

Cameron Simoncic, a second-grader from Greenville County, said he sprang into action when he got home from his classes at Ellen Woodside Elementary last Wednesday and found his father unresponsive in the kitchen.

“My dad has diabetes and whenever he has these episodes and whenever it happens, his brain can’t function,” Cameron told WSPA.

At first, Cameron attempted to call for help, but he couldn’t unlock his father’s phone. And when he ran to a neighbor’s home, no one answered the door.

“I got on my bike and tried to ride to my grandma’s,” he said of his next move.

The determined child crossed four lanes of traffic to get onto Highway 25, where his first-grade teacher, Keller Sutherland, happened to be driving home from school early. Before she left the school, she stopped at the vending machine for a pack of crackers — a snack that would come in handy later.

Sutherland, a mom of two, told The Post she found it “unusual that a little boy was biking down a busy highway.” She said her maternal instincts kicked in and she decided to pull over.

“There were so many people that passed by this child,” she recalled.

When she got closer to the boy, she realized it was Cameron. When she asked him why he was biking down the busy highway, he told her his dad was in trouble. “Cameron was extremely calm. That was so encouraging to me because it allowed both of us to do what we needed to do to get help,” she said.

Two other motorists also noticed the boy and called 911.

When emergency workers arrived, Cameron couldn’t remember his home address but said he could show Sutherland and EMTs how to get there. He got in Sutherland’s car and they successfully drove to his address.

After EMTs found Cameron’s unconscious father in the bathroom, they gave him an injection to normalize his blood sugar level. After the shot, Sutherland handed Cameron’s dad her pack of crackers, which helped him recover.

Sutherland said her encounter with Cameron was meant to be. She’d been having a rough day at work and even texted her friends asking them to pray for her because she didn’t feel as though she was making enough of a difference in her students’ lives.

“I truly believe this was not a coincidence,” Sutherland said.
