Thanks Makara for the info. Never heard of this until now. It seems you already have found the perpetrator!
Well, the best way is definitely getting all the DNA from the House of Horrors family and cross check with the childs bones DNA. Bingo!
Although there is no mention from the police or media about the connection between this House of Horrors family and the childs bone, I would hope that the police have already taken this step DNA checking. Thanks to this DNA age, it really helps made our life and mind a lot easier.
In the meantime, we can only continue to speculate.
If there are these Trudy family and the Colt family, there could really be more families like this out there.
There are two interesting timelines. In around Jun 2008, one of the children was taken to hospital, starved and badly bruised. This was the trigger when this House of Horrors was discovered. This June 2008 is close to the possible time when the child in the suitcase might have died since 2007, she could have died in 2008.
That seems to be the only time the House of Horrors family had a child going to the hospital. It is possible that this very angry adult who had caused this child to the hospital might had also killed and hid another child at around the same time within the House of Horrors family.
Talking about 2007 or 2008, there was an economic downturn, not sure if that might caused a lot of tension to many families and led to these tragedies around this time?
Another timeline is Trudy disappeared in around Mar 2015, as already mentioned by Makara, that is probably also the time the very first sighting of a suitcase in that area from some witnesses.
Trudys sister, Tania is the mastermind, she could be the one who got rid of the childs bones?
A family like this is almost impossible that there could be anyone who could come forward to say they know the child, in such a mess and surrounded with all the addicts or criminals.
