Attorney Ben Crump is set to announce the independent autopsy results for Nolan Wells, the 18-year-old whose death off the Mississippi Gulf Coast has sparked controversy.
Wells was found dead near Horn Island two days after going missing during the Fourth of July weekend.
Authorities initially ruled his death a drowning, but Crump has questioned that conclusion.
Crump has suggested that officials in Mississippi may be trying to conceal the true circumstances of Wells' death.
The family has also expressed doubts about the official narrative.
Reverend Al Sharpton and filmmaker Tyler Perry are each offering $50,000 for information leading to an arrest and conviction in the case, signaling that foul play is suspected.
Wells' mother has alleged that messages were deleted from her son's phone after his body was found.
Meanwhile, TMZ obtained video from Horn Island on July 4 that may show Wells in his final hours, bending over to grab a drink from a cooler.
Crump's announcement is expected to shed new light on the investigation.
