Witnesses who called 911 said they observed the woman get out of her car with a small child and walk over to the nearby Interstate 40 overpass, never to return, reported WREG.

A few minutes later, authorities got a call from a truck driver reporting that his vehicle was struck by 'a large object' that fell from the bridge.

Deputies who responded to the scene near Exit 93 found the bodies of Barker and her son.

Sheriff’s spokesperson Tom Maples told WKRN deputies are now trying to determine what might have motivated Barker to end her and her son's lives.
