A Limestone County sheriff's deputy probably thought he was just dealing with a routine traffic stop Wednesday, but it turned out to be something much bigger.

KWTX's Matthew Ablon reports that the deputy stopped a driver who sparked suspicion. When he refused to cooperate or consent to a search, backup and a K9 unit were called.

The K9 unit search resulted in the discovery of half a pound of marijuana. The driver was taken to jail without incident.
