   Patrolman Martin O'Brien and Patrolman Francis Mulvihill were shot and killed by subjects believed to be part of the Dillinger Gang.

   The officers were patrolling a rural section of Gary Road when they stopped to talk with four men standing next to a car. Without warning, the suspects opened fire with machine guns, striking both officers multiple times before fleeing the scene.

   Patrolman O'Brien was survived by his wife and three children.
