FORT HOOD, Texas -- Fort Hood is using hundreds more personnel Tuesday to search for a soldier missing since a Friday solo navigational training exercise.
Sergeant Lawrence Sprader of Prince George, Virginia, vanished after telling commanders by cell phone that he was lost but determined to finish the exercise.
About 800 troops joined dozens of civilian law officers today in the ground search, walking in marked grid areas. Two Black Hawk helicopters are also being used.
Passing motorists reported seeing a soldier matching Sprader's description near a road Friday evening. That, and his score card from the exercise, were the last signs of him.
Commanders and family members say Sprader is a model soldier, and they have no reason to believe he intentionally disappeared.
Sprader returned from Iraq in September. He had no pending orders for redeployment.
