Echoes of Daniel in Wallman case
REX and David Wallman left home 10 minutes after their 14-year-old sister did more than 40 years ago.
They are still looking for her.
The Mackay brothers travelled more than 900km to join the Walk for Daniel with their family on Friday at Palmwoods.
They were there to support the Morcombes - but more importantly "bang the drum" about their sister, Marilyn (pictured), whose disappearance on March 21, 1972, from the back of a cane paddock became one of Mackay's longest running mysteries.
The brothers knew straight away she had been taken in a matter of just minutes.
"Marilyn was halfway along the road," Rex told the Daily at the walk.
"She was on one side of the hill and we are on the other side of the hill."
When the boys arrived where Marilyn should have been, all that was left was her bike.
"From that day on we have been searching for her," Rex said.
The situation is eerily similar to the Daniel Morcombe case in that he was allegedly snatched in a matter of moments.
Rex and David have worked with a succession of senior detectives - and are nothing but full of praise for police who have worked in their own time, even into retirement - to try to crack the case.
But they are incredibly frustrated that there are no detectives in Mackay to probe new leads and information generated by their efforts in raising Marilyn's case.
"We are just totally beside ourselves with frustration because we can't get anything done," Rex said.
On Friday, the family spoke with Premier Campbell Newman, who they said seemed very interested in their case.
But they say Mackay desperately needs more detectives - and the promised cold-case officer.
They have vowed to keep fighting, just as the Morcombes have done.
