An unidentified ute could help solve the mysterious disappearance of two elderly campers who vanished in rugged bushland without a trace. Russell Hill, 74, and Carol Clay, 73, went camping in secret during a lurid decades-long affair on March 19 in the rugged bushland of the Wonnangatta Valley in Victoria's East Gippsland region. On Friday, detectives from Victoria Police's Missing Persons Squad made the extraordinary public appeal in the hope of finding a white dual cab ute that was spotted in the area at about the time the campers vanished. Victorian detectives have released a new map of an area where a mystery white ute was spotted on the day the campers went missing
