VALDOSTA, Ga. -- New developments could come Wednesday in the high-profile death of Kendrick Johnson, 17.
Johnson was found dead inside a rolled-up gym mat at his high school on January 11.
The teenager's parents and their attorney believe Johnson was murdered, but authorities stand by their findings in the case.
They contend Johnson suffocated inside the mat while trying to retrieve a shoe.
Johnson's parents, though, would like officials to release complete surveillance footage from inside the gymnasium.
They believe there were four cameras inside the gym that will show how Johnson ended up inside the gym mat.
A short clip of surveillance video was released recently that shows Johnson was not alone in the gym.
But no footage has surfaced that specifically zones in on what might have led to his death.
Johnson's family is also asking the court for a coroner's inquest.
A private autopsy showed the teen's organs were missing and replaced with newspaper. That same autopsy showed Johnson died from non-accidental blunt force trauma.
The attorney for the family also argues Johnson's clothes from the day of his death are missing and that police contaminated the scene after finding his body.
The Georgia Bureau of Investigation said it stands by the findings of its medical examiner.
