Officials say a 28-year-old Arkansas man has been arrested in the killings of a married couple in front of their children at Devil’s Den State Park over the weekend.

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.
