A 15 year old is accused of killing his aunt and injuring his mother at their Antioch home.
Metro Nashville Police were called to the home on Rocky Top Court last night around 7:30.
46 year old Michelle Bergman was found dead.
37 year old Rebecca Bergman was stabbed and treated and released from Vanderbilt University Medical Center late last night.
Matthew Bergman was at home when officers arrived and was taken into custody.
Officers say he killed Michelle Bergman early yesterday morning and then watched two young children at the home all day until his mother came home.
When she asked about her sister, officers say that is when he stabbed his mother.
Matthew Bergman is believed to have had arguments with his aunt Sunday and Monday.
He is charged with murder.
