I doubt very much it was a gang that did the deed.
The below is a quote from Spencer Browne a reknowned reporter of the day
"We were together in South Africa many nights, and lying out under the stars we often talked of the Gatton tragedy, and we had the opinion that it was the job of one man and a bad 'un who had slipped through the hands of the police. And we both believed that if F. C. Urquhart had had his way the story of the tragedy would have been made plain."
I also doubt that murder was intended but things just got out of hand somehow.
I believe there was a huge cover up from the Vatican down. The then Qld Government (chiefly masons), certain townspeople and the police were also involved in supressing information.
I am willing and happy to share any and all the information I have compiled in the hope of proving who the culprit actually was.
If you are willing to do the same I would be most grateful and it may help to clear this matter up once and for all.
I know some of my ideas seem a little bit strange but you must remember once everything else has been ruled out whatever remains however strange it may seem is most likely, or must be the answer.
PS would you happen to have come across a picture of Sergeant Arrell and/or the enigmatic Thomas Day.
Certainly one of the greatest mysteries in this country's history, along with the Beaumont Children and the Wanda Beach murders.
The passage of time makes this cold case hopeless to re-open unfortunately.
