UPDATED: Franklin County authorities said Michael Hill, 36, and his son, David Hill, 16, were located about 6:30 p.m. Thursday where they had been camping in the Moselle area, east of St. Clair. 

The two appeared to be unharmed, Sheriff Gary Toelke said. 

According to the sheriff, the son went to a home in the area about 5 p.m. to ask for water and the resident later called the sheriff's office and said the teen was last seen walking west along the railroad tracks.

Deputies responded to the area and began walking the tracks. At a point near Mill Spring Road, they noticed footprints in the mud leading away from the tracks. They followed them and heard people talking in the woods.  

There were few other details available as of this post but the father told deputies they were heading for Branson, Mo., the sheriff said. 

The sheriff said the two, from Illinois, had been staying in a tent in the area.

Authorities have been searching for the two since they were last seen July 2 in the Pacific Palisades area in western St. Louis County.
