The man arrested over the suspicious disappearance of elderly campers who were having a secret affair may have sold his trailer, with police urging the new owner to come forward.
Jetstar pilot Gregory Lynn, 55, has been held in custody since Monday and is being questioned about the campers, who vanished 20 months ago in Victoria's high country.
Flynn was arrested on Monday night by specialist police at a remote campsite in Arbuckle Junction, 280km northeast of Melbourne.
His Nissan Patrol four-wheel-drive has been seized but police are yet to track down the man's trailer.
Detectives believe the silver-coloured trailer was sold last year between March and July and have issued an appeal to anyone who bought one at that time matching the description to come forward, Chief Commissioner Shane Patton said.
'If they've received one or purchased one and ... they don't absolutely know who they purchased it from or how they came into possession of it - there might be something suss about it - if they could contact Crime Stoppers that would be fantastic,' he told Melbourne radio 3AW on Thursday.

The 4WD (pictured in a police sketch) has roof racks, side steps, off-road tyres and a bulbar. The box trailer is 'fairly standard' but has been fitted with 'off-road wheels', police said
Mr Patton confirmed the man, a stood-down check captain with budget airline Jetstar, was spoken to by police previously before his dramatic arrest.
The Victoria Police boss stressed there was 'no urgency' to lay charges against him, noting a person can be held in custody for 'a reasonable time' with no set limit under the Crimes Act.
