Police have released new details about their search for a suspect after an Arkansas couple were killed while hiking with their two small children.
Clinton David Brink, 43, and his wife, Cristen Amanda Brink, 41, were hiking with their children at Devil's Den State Park on July 26 when they were attacked, according to a news release from the Arkansas State Police.
The family had recently moved to the area from another state.
Arkansas State Police released a composite sketch July 28 of the man sought for questioning in the deaths. The suspect likely sustained an injury in the attack, police said, though they did not specify the severity or type of injury.
The man in the sketch was seen in the park that day, and investigators want help from the public in identifying him, police said.
The suspect remains at large. The couple's children, ages 7 and 9, were not harmed and are now with relatives.
On July 27, Arkansas State Police issued an updated description of a suspect, describing a white man with a medium build wearing a long-sleeved shirt with the sleeves rolled up; dark pants, a dark baseball cap and sunglasses. The man also had a black backpack and wore fingerless gloves, police said, and was seen driving toward a park exit in a black, four-door sedan, possibly a Mazda, with a license plate possibly covered with electrical or duct tape.
Police are seeking additional information and asking anyone who was in the park Saturday, July 26 to check cellphone photos and videos for possible images of the suspect, as well as asking area residents for security and surveillance footage.
"We are using all available resources to apprehend this suspect and bring him to justice," State Police Col. Mike Hagar previously said in a statement.
