This man was attacked and presumably killed by an unseen creature in the mist.
This man owned an El Camino, and is one of the patrons trapped in the Grocery Store when the Mist begins to spread across the town outside. When Dan Miller runs into the store, screaming about something in the mist taking John Lee, this man runs out of the store to his car. He tries to get into his car, when the Mist engulfs the parking lot. The man is then attacked and presumably killed by an unseen creature in the mist.
