BEACHPORT, Australia - Police in South Australia are hoping to stir up new leads in the case of a Saskatchewan man who vanished 45 years ago while on a working holiday there.

Investigators say Gordon Rogers was last seen at a party in the town of Beachport, about 400 kilometres southeast of Adelaide, in the early morning hours of Aug. 2, 1970. He was 20 at the time.

Police say they suspect he was murdered.

Now a $200,000 reward is being offered to anyone who provides information that leads to his remains or an arrest in the case.

Rogers' disappearance is among more than 100 cold cases featured in a campaign that South Australian police say has generated hundreds of tips since February.

They say Rogers arrived in Sydney on a 12-month visa in March 1970 and travelled a bit before taking a labourer job with the Woods and Forest Department.
