A picture and a sketch show a person that the state police are seeking to question in the deaths of Clinton David Brink, 43, and Cristen Amanda Brink, 41, in Devil’s Den State Park. Their daughters, 7 and 9, were not physically harmed.

The couple were hiking with their two daughters on Saturday when they were attacked, according to the police, who asked for help in searching for the killer.
