Thanks for sharing, Libstak. Very interesting.
Ok I'm writing this in a rush ( I'm still on the campus, doesn't have much time to write ), so my english won't be too pretty.

- The changing MO between the two killings. I don't think it is necessarily odd, the simplest explanations are often the best and as was already noted a lack of time, something spooking the killer, panic or a first kill in an escalating series are all reasons why a decapitation did not occur in the first killing but did in the second.
I agree, well said. In most cases the changing MO might be sign that the crimes were committed by different killers. However in this case I am convinced that the same killer murdered both Angela and Melanie. There's just too similarities, I'm sure they were killed by the same man ( or men, always a possibility that more than one person was involved. Like I wrote in my first reply: since Melanie wasn't decapitated then it's possible that decapitation may not be part of the killer's MO, and that the reason why he decapitated Angela was because he might have had a personal grudge against her. Only how I feel. Or he changed his MO to make people believe that more than one killer was in the area, again unusual but possible. I also feels like the murder of Diana, weeks before the death of Angela, is strong evidence that a serial killer was indeed in the area.

- The lack of further cases after these two is also curious, the basic principle of a female alone in a secluded area near water should at the least apply, the bikes too BUT two kills is not enough to put a concrete MO on a killer, particularly a fledgling even these key indicators could be abandoned if the killer perceives they are now too risky.
I disagree, two kills can be enough to put a concrete MO on a killer. Well, in most cases. It's a little bit more complicated for this case, but usually we can see a MO or patterns after two murders. The stolen bikes is really strange. Maybe the killer wanted to keep souvenirs, maybe it was his signature ( way to feel good, way to fill a need ), hell maybe it was the reason why he killed both girls ( but I doubt it ). Keeping these bikes could have been very risky, I really wonder why he ( or they ) did this.

The investigation and knowledge that police have his DNA could be cause for a radical shift in behaviour - he would not have been likely to have stopped but as I said a "fledgling" would be far more open to altering their methodology even in radical ways - or a means to not leave behind a body to be found may have occurred and therefore this guy could be quite active even now.
I highly agree with everything you wrote there.

So why no further public appeals for information? Is the investigation ongoing or sitting on a backburner (in a coldcase file covered in dust somewhere?).
Sadly the case is sitting somewhere and is not being seriously investigated ( as far as I know ), and it's really sad. A tragedy. Very unfair to the families of the victims.
I'm trying to find more infos, such a fascinating case !
