It seems that DH was one of LM's closest friends at the time, so he probably knew he was with her most nights without actually being in their company (ie, LM telling him in school he was with her and DH seeing them together most nights without actually being in their company). Like I said, I'm surprised ADT never asked DH if it was common for LM to meet up with him during that particular time when LM was dating Jodi.
Well, you certainly have an answer to everything, Mr Apples!
Anyway, lets go back to what happened after the murder and what was going on in LM mind, if guilty!
OK, Luke has rushed to kill Jodi and indeed she is dead within a good half hour of the last text between them, now what?
Rationally Luke must have thought, 'right ! job done, now to sneak home as soon as possible and dispose of my blood stained clothing, hopefully without being seen or recognized by anyone. I'll shower to get rid of any forensic evidence then phone Jodi's house to say that she hasn't turned up. Yes thats it, brilliant, speed home unseen, shower, dispose of murder clothing then phone Jodi's house! All evidence destroyed and no forensics on me, nothing to tie me to the murder scene, by golly i'm good! You're a genius Luke Muir Mitchell, a genius!!!!'..............
..........'No wait!.. just wait up there a minute, Mitchell! wait up you numbskull !..yes, thats it, thats it! ..why dont I just stroll onto Newbattle Road in my murder clothes for all to see! I could stand there for about an hour to let as many people see what i'm wearing and hopefully remember my face too. Who knows, someone may even pass by who actually knows me, they may even notice any small blood stains on my clothing! Yes, lets give the police a sporting chance too, if Jodi's body is found quickly they might even lift me before I get home.Yes, now i'm talking! That indeed sounds like a plan for sure my son! ..Phew!!! I almost messed up before I got started! What in the name of god was I thinking there, rush home and get cleaned up ASAP? Gee whizz!.. you are a numpty, Muir!!''...............
............
Is this what went through LM mind as he stood over Jodi's body at the locus, Mr Apples?
In hind sight, do you think he made the right decision?
I for one cant fathom out what his plan was!!
