DES MOINES, IA—State trooper Tracy Bohlen approached a stalled truck thinking he was about to break up a fight. To his surprise, a teenage boy opened the car door and frantically told him his dad, Patrick Roark, was having a heart attack. The officer quickly moved into action and performed CPR on the man right in the middle of the interstate. While others rushed to help Tracey and the man, a kind nurse comforted his traumatized son and took care of the family for the rest of the day. We thank God for such selfless people—Wow!
