Simbi, I doubt that because I don't know of any reason the mom or dad would be a target for a hit, and in addition, why the rest of the family would be killed.
It looks to me as though the perp entered the home to see what he could get, and then had nowhere else to go.
The location of the home is interesting...it was one of four situated between two railway stations- I think, less that a mile from either one. Evidence from the perp's clothing indicated that he was a traveler (although, it's possible the clothing could have been stolen, but even so, the other circumstances indicate he likely did travel around.)
The family was said to have been shopping in a shopping arcade near one of those stations near their home in the "early evening of the 30th" so, it's possible they could have been stalked from there, or the perp simply passed by on the way to the other station, and for some reason, chose their home to enter.
Also, the perp must have had other clothing to change into. I think it's likely he came with another bag... unless he replaced what he'd been wearing with clothing belonging to the dad.
There's info. that " while in school, (the dad) was active in producing puppeton animation and acting in theater work."
That's interesting because it's reported that the perp accessed a theater web site.
I don't know if there could be a connection there (that the perp was familiar- or had some association- with the dad through that), or if it's simply a coincidence, or if the info. is mistaken that it was the perp who accessed the site as opposed to the dad.
I think when there's nowhere to go in an investigation, then authorities should start over, and reevaluate the evidence...maybe take leads that might appeared to have dead-ended at the time, a little further.
It's possible that some little something could have been missed, or even possible that info they've gone on is actually incorrect.
Fortunately, they have DNA if and when a POI/suspect emerges.
Robbery/assault POI's/suspects should also be considered for comparison.
