Clinton and Cristen Brink have recently moved to Arkansas with their daughters and decide to go for a hike in Devils Den State Park.

Without warning, the family is ambushed on a hiking trail by a man with a knife. 43-year-old Clinton fights with the man as 41-year-old Cristen runs with their daughters, 9-year-old Arianna and 7-year-old Christina, until they are a safe distance away from where the attack is taking place.

Cristen tells the girls to run towards where they parked their car and get help. Cristen then returns to help her husband. The girls do as they are told, and some hikers in the park find them and take them to the entrance to the park to tell a ranger what happened.

Joseph Scott Morgan and Dave Mack discuss this shocking case and break down the forensic evidence that is used to identify the suspect, Andrew McGann, and what evidence directly ties him to the crime.
