A woman whose apartment Mr Jones had stayed in would attend court on March 14, Ms McMillan said. She had been providing information to his family and friends in New Zealand throughout the case.
Mr Jones, 56, was stabbed to death in his hotel room at the Thai beach resort of Pattaya while on holiday in August 2011.
Former Syrian army commando Mohamad Shanar Ryad was charged with his murder.
Ryad admitted killing Mr Jones but said he had reacted after the New Zealander had tried to rape him.
Mr Yeatman had told the court Mr Jones would never attack someone and was incapacitated with a shoulder injury.
It's understood Ryad plans to admit it was a botched robbery and drop his allegations against Mr Jones.
Mr Jones was the New Zealand president of the World Croquet Federation and was on his way home from a world croquet tournament in London when he was killed.
