It absolutely was BG.
Forensics falls apart very quickly, paramedics trampled the whole scene trying to save Jill's life and whatever was on the coat also fell apart after more than a year till it was taken in.
The "hitman" and "criminal underground" accusations were all followed and all fell apart, because they didn't make sense.
The call from a "hitman" also said Jill would be the first, yet no other journalist was killed. It was a prank. No organisation claimed the kill and they absolutely do claim kills. A hitman wouldn't have killed in such a manner.
No one can outight say it was BG, because BG sues for it and he has been paid handsomely by papers in settlements. He has a low IQ, but he is capable of planning, cunning and lying. I mean, he used many aliases, pretended to be police, even obtained a genuine id or some such and gun. Clearly not too dumb to plan, lie and execute a plan.
His ex-wife fled home to Japan to escape him and has stated that he is capable of murder.
It was clear from the start that it was a "loner, stalker" type. About 4 calls came in the first month after the killing pointing towards BG, but because he used many aliases it wasn't instantly clear that the same man was meant.

Pretty enlightening article, how anyone can doubt it was BG is beyond me. It's enough to read the first few paragraphs, but overall great piece and very informative.
