(Undated) -- Surveillance video taken at a Georgia high school where a student was found dead apparently doesn't answer how he died. The video released last night shows Kendrick Johnson earlier this year as he walked into the gym and onto the basketball court, but does not show anything leading up to his death. Johnson family attorney Chevene King tells ABC News they're hopeful.
The 17-year-old's body was found rolled up in a gym mat at Lowndes High School in Valdosta, Georgia in January. Johnson's parents believe he was murdered.
Jacquelyn Johnson is thankful the surveillance video was released.
