Clinton David Brin and his wife, Cristen Amanda Brink, were "fatally attacked" while out hiking with their two daughters at Devil's Den State Park, police said.

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.
