Teacher and former beauty queen Tara Grinstead vanishes from her Georgia home. There is no sign of forced entry. There is no sign of a struggle, but some things were out of place. Grinstead's bedside clock was found under her bed, and a broken lamp was propped against the wall on her nightstand. 

The 30-year-old attended a beauty pageant and a cookout with co-workers before  going home.  Friends and family called Grinstead the next day, but couldn't reach her. When Grinstead did not show up to teach at Irwin County High school, co-workers called police.   

Some 12 years later, Grinstead's remains are found in a pecan orchard and two of her past students charged with her murder. Today on Body Bags,  forensics expert Joseph Scott Morgan looks at what details may have been overlooked at the time of Tara's disappearance.
