Maureen Braddy and Allan Whyte: 50 years on, families still search for answers

It has been 50 years since teens Maureen Braddy and Allan Whyte vanished, and their families are still waiting for answers.

Maureen, 16, and her 17-year-old boyfriend Allan left a YMCA dance in California Gully, Bendigo, in central Victoria, on November 23, 1968.

A witness has told police she saw them on board the last tram heading home.

Gunshots were then allegedly heard at the Braddy family home.

Maureen's father, Stan Braddy, has been named as a suspect but has never been charged and has denied any involvement in the teens' disappearance.

Now aged 88, he has dementia and lives in a retirement home in Bendigo.

Maureen's sister Lynn believes her sister was buried inside a well in their backyard, which has since been built over.

The Whytes suspect Allan was thrown down a mineshaft.

"You can't even lay a flower down, you can't even go and talk to them," Lynn said.

Allan's brother Kevin said he wanted "closure".

"Give them a decent burial, bury them together," he said.

Police are hoping a $1 million reward will entice somebody with critical information about the teens' disappearance to come forward.

"Before I die, I'd like to find his body and give him a decent burial," Kevin Whyte said.

Anybody with information is urged to contact Crime Stoppers on 1800 333 000.
