Aug. 14 (UPI) -- The man charged with fatally stabbing a couple with their kids at Devil's Den State Park in Arkansas pleaded not guilty Thursday to two counts of capital murder.

Andrew James McGann, a former teacher, has been alleged to have randomly attacked and killed Clinton and Cristen Brink in July as they were hiking the park with their daughters, aged 7 and 9.

The girls were not physically injured and are with family members.

McGann was arrested by special agents with the Arkansas State Police after a five-day manhunt resulting in his being taken into custody while receiving a haircut in Springdale, Ark., around 30 miles north of Devil's Den State Park.

McGann, currently represented by a public defender, is being held in custody without bond. The prosecution will seek the death penalty if McGann is convicted.
