The trial of Thomas Greenwood got underway in a rare Saturday court session in Coffee County Circuit Court. Greenwood is accused of killing his former girlfriend’s 2-year-old son, Hayden Gage West at a residence on Circle Drive in Tullahoma in March 2010. He told investigators that he suffered a seizure, which caused the child to hit his head on a bed rail, but investigators disagree saying that that wasn’t the case. The state medical examiner determined that the child died of multiple injuries, which resulted in a homicide. Greenwood has been held in the Coffee County Jail since his arrest. The trial in which the jury is sequestered took Sunday off and resumed today.
