LITTLE ROCK, Ark. (AP) — Arkansas police released a photo Tuesday of a man wanted for questioning in the investigation into the weekend killing of a married couple in front of their children at Devil’s Den State Park.

The image released by state police doesn’t show the man’s face, and comes a day after police released a composite sketch of a person of interest. Details about the attack, including how the couple was killed or a motive for the killing, remained scarce.

Police say killer likely injured during attack

Clinton David Brink, 43, and Cristen Amanda Brink, 41, were found dead on a walking trail Saturday at Devil’s Den, 2,500-acre state park in northwest Arkansas. Their daughters, who are 7 and 9, were not hurt and are being cared for by family members, authorities have said.

Police have not said how the couple were killed, but said Monday night the killer likely was injured during the attack.
