GREENEVILLE, Tenn. (AP) - An East Tennessee judge has sentenced a Miami man to more than 21 years in federal prison for carjacking and interstate car theft in a case that involved the violent abduction of his infant son.
    
David Jackson was convicted in March for his role in the abduction of his son from the child's mother in Greene County in July 2010. The child was the subject of a nationwide Amber Alert and was later found in Miami, unharmed. Two women who were with Jackson pleaded guilty to federal kidnapping charges.
    
The U.S. Attorney's office said in a news release that U.S. District Judge J. Ronnie Greer in Greeneville noted during sentencing on Monday that Jackson was a career criminal and was a danger to the public.
