A summer bike ride near Fruitland, Iowa, turned into an emergency rescue for two teenagers who found an elderly woman stranded outside for more than 16 hours.

KWQC News reported that Gunner Skidmore and Kohen Chick were riding toward Muscatine when Chick spotted what looked like someone lying in a yard. The two turned around to check.

“I said, ‘Hey ma’am, are you OK?'” Skidmore recalled. “She was like, ‘Yeah, I need help. Call 911.'”

The boys called Gunner’s mother, who went to the scene and contacted emergency responders. They later learned the woman had been outside since about 5 p.m. the previous evening.

“She didn’t have her phone or water or anything. She was there for like 16-plus hours,” Skidmore said.

According to the teens, the woman appeared frightened and exhausted after spending the night outdoors.

“She was like scared. You could just tell because like her face, she was covered in all these bugs and stuff,” Chick said.

The woman told the boys she had fallen while feeding her horse. Unable to get help, she reportedly rolled from her backyard to the front of her property so someone might see her.

Skidmore said the timing mattered.

“A few more hours and she definitely like wouldn’t have made it,” he said.

The woman was taken to a hospital in Muscatine for treatment. KWQC News reported that while she recovers, Gunner’s mother has stayed in touch with the woman’s family and has been helping care for her horse by making sure it has food and water. She also plans to welcome the woman home with a homemade lasagna when she leaves the hospital.
