Yes, I have always hoped someday I might have a chance to discuss this case with Douglas.
I think of another Hobbs - Jerry Hobbs, who was charged with the murder of his daughter and her playmate. Police started with an enraged parent theory, similar to the one Douglas has laid out in the WM3 case. Jerry Hobbs, a violent alcoholic who had just gotten out of prison, was plausible. But, there was semen on (not inside) the body of one of the victims, which was eventually linked to a sexual predator. Jerry Hobbs is innocent.
In the WM3 case, the bodies were dumped in water, degrading the forensic evidence. But the overall crime looks very similar, to my mind. Why would an enraged parent remove the victims' clothing? Douglas came up with a theory that Hobbs caught the boys in some kind of sex play, which is possible, but it is speculation. I think sexual homicide by a predator/stranger is the straightest line between the dots.
I agree it is unlikely the case will ever be solved at this point. It is enough to conclude that whoever did it, it was not the WM3.
