Rescuers found a missing father and his two children in the Congaree National Park early Tuesday morning.

The park held a briefing at 9 a.m.

National Park Service Ranger Jared Gurtler was the first officer to make contact with Kimbler and his two children.

Gurtler was out in the park around 4:30 a.m. on foot with just a flashlight. Since he is based at Congaree, he is familiar with all the trails, even at night.

"The best opportunity to hear human voices in the wilderness is at night," Gurtler said. "At night, no birds are singing and the human voices can be heard at that time."
