A Garrett man is in the hospital after suffering a head injury in a solo crash Monday afternoon. DeKalb County deputies say 73-year-old, Thomas Cook was eastbound in the 1700 block of County Road 60 when his vehicle left the roadway, continued through a ditch, over a driveway and eventually crashed into a patch of trees. Cook reportedly told authorities he had fallen asleep, which is what caused the accident. Cook was taken to an area hospital for treatment. The investigation into the accident continues.
