Clinton David Brink, 43, and Cristen Amanda Brink, 41, were found dead Saturday at the park in Washington County, police said. They were hiking with their daughters, ages 7 and 9.

There are no security cameras in use anywhere in Devil's Den State Park, so when authorities began a search for a suspect in a double homicide last month, they relied heavily on members of the public to submit photos and videos to help in the investigation.
