Finding a lost wedding ring along a snowy road is hard enough. But a Californian also has to track down the man it belongs to.

Douglas Benedetti said he met the man but does not know his name or phone number. Mr Benedetti said the man was searching for the ring on the shoulder of Interstate 80 near Kingvale in the Sierra earlier this month. He told Mr Benedetti he had lost the ring while putting chains on his vehicle.

Mr Benedetti wants to return the ring. But all he has to go on is its inscription: Lisa, 5th June, 2010.
