Police search property in Casino, NSW for remains of missing father-of-two Greg Dufty

The search for the body of missing father-of-two Greg Dufty has spread from Queensland to a property in the northern NSW town of Casino.

A man faced Southport Magistrates Court on Monday charged with being an accessory to murder while three people have already been charged with Mr Dufty's murder.
