Two Franklin County deputies hiked five to six miles to locate a woman and her son who went missing Wednesday night in Meramec State Park.

The woman, her husband and 8-year-old son had gone hiking on a trail in the state park about 7:30 p.m. and became lost, Sheriff Gary Toelke said.

Toelke said the husband told his wife and son to stay where they were while he sought a location where he could call out on his cellphone.

The sheriff’s office communication center received the call about 9:30 p.m. and dispatched deputies and firefighters from Sullivan.

While driving on Highway 185, a deputy saw the husband who explained what happened.

A dispatcher made contact with the woman on her cellphone but the signal was weak and her battery was low so she was unable to give her location, Toelke said.

The deputies began walking the trail and eventually found the woman and son at 11:28 p.m., the sheriff reported.

Due to the location, deputies called for a Sullivan Fire District crew to send a rescue boat to pick up the woman and child.

None of the family members, who live in Sullivan, were injured, Toelke said.
