Dixson’s cab was found Friday morning at the Jackson residence on Forsyth-Yatesvile Road. His body was found later that day just over a mile from that home.At last report, a suspect was being held for questioning and is expected to be charged. Though he has not been named by authorities, it is known that a manhunt was launched Friday for Jamarris Williams who was found at Fuller’s Trailer Park and taken in for questioning.Members of the Dixson family have said the cabbie was robbed and abducted and that Williams’ brother notified authorities after finding blood in his residence.
