Three months after a missing teacher's body was found in a wooded area of south Charlotte, an autopsy is revealing new details about her death.
Bianca Tanner's body was found in early July in a wooded area off of Calico Crossing Lane.
Tanner, 31, was teacher in Guilford County and had recently moved to Charlotte with her son to try and land a teaching job.
Her boyfriend, Angelo Grayson Smith Jr, was indicted on first degree murder on July 7.
Never miss a local story.
Police say Smith intentionally killed Tanner after the two got into an argument at his apartment and then hid her body to conceal the crime.
An autopsy completed by the Mecklenburg County Medical Examiner on July 3 was released on Friday.
The autopsy lists Tanner's death as "undetermined trauma."
Sources say Smith possibly went to visit a friend the night Tanner disappeared and left Tanner's 3-year-old son home alone.
Smith was taken into custody by US Marshals in Chicago after Charlotte police wanted to question him in the case.
Sources close to the investigation have told WBTV that Smith has admitted to killing Tanner.
