An independent autopsy shows the death of a 17-year-old Lowndes County High School wrestler was not accidental, according to CNN.

The report said that Kendrick Johnson died in January as the result of “unexplained, apparent non-accidental, blunt force trauma,” CNN reported.

That contradicts the finding of the state’s medical examiner with the GBI’s Crime Lab, which deemed the teen’s death a result of positional asphyxia, leading the Lowndes County Sheriff’s Office to call the death an accident.

Johnson was found Jan. 11 rolled up headfirst in a wrestling mat at a high school gym.

“A complete autopsy was done, and we’re standing by our findings,” GBI spokeswoman Sherry Lang told the AJC on Tuesday.

Johnson’s family attorney is sending the results from the Orlando forensic pathologist to the U.S. Justice Department’s Civil Rights Division, CNN reported.
