Sullivan County deputies are investigating a burglary at a Fort Henry Drive convenience store. Someone drove a vehicle through the window of the Sunoco and took money from the in-store ATM. Investigators found debris from a car inside the business. Witnesses reported seeing a gold colored Saturn sitting in front of the store. Deputies stopped a gold Saturn with visible front end damage a few hours later. They found glass inside, and blood on the drivers side. Three people were detained, questioned and released after police determined they weren't in the car at the time of the robbery. (jb)
