Police say the suspect accused of killing the couple as they hiked with their 7- and 9-year-old daughters is still at large.

Relatives of Clinton and Cristen Brink described them as "heroes" for protecting their daughters, both of whom were left unharmed in the attack.

Clinton David Brink, 43, and Cristen Amanda Brink, 41, were found dead Saturday at Devil’s Den State Park in Washington County in a suspected homicide, Arkansas State Police said. Their daughters, who are 7 and 9, were not hurt and are being cared for by family members.
