Yes, in my opinion the Police were too stupid to fathom this out. Once they had allowed the crime scene to be contaminated for 7 hours, they then failed to search the houses of anyone except Mitchell because Dobbie had already decided he must have done it. They were suffering from "confirmation bias" from the first minute of the investigation. Murders such as those carried out by Tobin and Sinclair had no real motive apart from killing their victims. Now a character like either of them did not just happen to be hiding in the trees carrying weapons, over the wall at the path at about 5pm in broad daylight with dog walkers and cyclists around. Killers like the above 2 were smart, they abducted their victims and took them where there was no chance of other people being around.
The "moped boys" took 5 days to tell the Police it was them on the moped the day of the murder. The Police were too thick to question the motives and statements of 2 people you wouldn't trust to keep 50p for you. These 2 were never identified by anyone whilst on the moped. The fact is, nobody knows WHO was on that moped.
To return back to motive. Mitchell had no motive to kill his girlfriend. Did the Police investigate anyone who might have had a motive? No they didn't. These Police were stupid. They had no experience of similar murders because they're rare in Scotland. When the DNA tests failed to match Mitchell they should have called in the FBI as this case was out of their league. They missed several clues and failed to identify other suspects. They also missed the most obvious clue of all.......the victim's hair was pulled out at the roots. That is a highly unusual facet of murders carried out by men. In fact I do not even know of one previous murder case where the victim sustained such an injury. Tobin and Sinclair did even worse things to their victims but pulling their hair out at the roots was not one of them. IMO the killer of Jodi Jones was not a man, it was a female. Men do not pull women's hair out, they have other sick depraved evil things in their heads. Women very rarely commit murders and almost never when there is no motive. In my opinion, a female with a motive killed Jodi. That is why there were no signs of sexual assault and why there were several female DNA profiles found.
Do you think the killer walked back towards Newbattle, went along the main road past traffic and people, covered in blood? Obviously NOT. Do you think the killer ran across that main road risking being seen and going along the side of the small river behind the houses where Mitchell lived? Obviously NOT. Do you think the killer walked back towards Easthouses onto the main road? Obviously NOT. Hiding in the woods across at the golf course and College wouldn't be a good option either with the possibility of Police swarming in once Jodi had been reported missing then found. So how did the killer get away undetected and witnessed by nobody, not even a dog walker? There was people around......the cyclist who heard noises over the wall. A witness who saw the moped at the V. Others would have been around walking dogs etc, but not one person saw anybody in a hurry looking agitated or with blood on them. WHY ??
The killer had plenty time to clean up any evidence of committing a murder, because only Mitchell and his house was searched. The Police were done up like kippers. They just didn't have the brains or experience to figure out the puzzle because they were obsessed with Mitchell. Mitchell did not do it. No DNA or blood at the scene or in his house makes it impossible. Some people say maybe he cleaned up in the river behind his house. So he did the murder at 515pm, got to the river across the main road at 530pm after running through the trees and across the main road without anyone seeing him covered in blood, spent 10 minutes cleaning up, in time to be witnessed by other youths near the Abbey in Newbattle at 545-550pm? What did he do with the bloodstained clothes? He had spare clothes in a backpack and changed by the river? See how stupid this theory is? It's just not realistic at all.
