Mother seeks federal investigation after son was killed by police cruiser then buried without her knowing

The family of a man who was fatally struck by an off-duty police officer's SUV — then buried without their knowledge — is calling for a federal investigation.

Dexter Wade, 37, was killed on March 5, according to his death certificate, less than an hour after he left home following an argument. Despite his mother, Bettersten Wade, reporting him missing to the Jackson Police Department days later, she said she wasn't informed of his death until Aug. 24, nearly six months after he died.

"He just disappeared off the face of the Earth and nobody knew where he was. None of his friends, nobody," Wade said.
