Barrie Police are resuming their ground search for a missing 15-year-old boy who was last seen on Thanksgiving day.

Investigators say they want to make sure the area where Brandon Crisp was last seen has been thoroughly searched. The boy was last spotted on the Oro Rail Trail between 2nd and 3rd Line.

Police will also be questioning hikers and drivers passing through the area and continue to analyze data on his Xbox gaming console for clues.

The boy's parents say Brandon left their home after getting into an argument about his video gaming habits.
