A Christmas Day argument between a mother and her son ended when he choked his mother unconscious.

Whitfield County deputies arrived at the Salem Way home about 6:30pm to find Marilyn Flanagan unconscious. Her son, Scott Flanagan, was arguing with her and making threatening statements, according to the arrest report.

The two wrestled over a cell phone that was being used by the mother to attempt to call 911. That's when he choked his mother, the deputy reported.

The mother was transported to a local hospital for examination and treatment.

Scott Flanagan was charged with aggravated assault and obstructing an emergency call.
