To my knowledge there were no defensive wounds, suggesting Luke tied her up to begin with.
I think if Luke's movements are accounted for from 1745-2100 as you claim there must have been only a small window of opportunity for him to clean himself up, ditch the coat and the knife and wash himself. It puts Corinne in the picture-allegedly-as an accessory.
OK thanks Steve,but if I may say so,you are simply not looking deeply enough into the events/scenario. I will give you my thoughts.
What I have been trying to draw out of you is,when did Luke return home after the murder and give Corinne the bombshell news that he had killed Jodi and ask for her help? Now surely we can agree that it was at least sometime that evening,right? So just what are the options?
Option 1.Between 5.30-5.40 [Jodi was still alive at 5.15 as witnessed by Leonard Kelly,so had still to be mutilated.Hence the killer could not have left the scene till about 5.20 If it was Luke he would take about ten minutes to get home,hence 5.30 before he gets back home]
Option 2.Witnesses Fleming and Walsh actually see Luke at 5.50 on his way home,he is then seen near his house sitting on a wall around 6.05 then again between 6.20-30,so could have sneaked in at this time for fifteen or twenty minutes.
Option 3.Between 6.35 and 7.00 when he is waiting for David High.
Option 4.At 9.00 when he returns from the Abbey.
OK,what about option 1,? Well as we can see time is very limited,and we have to believe that Luke went in,told his mother the shattering news of what he had done,change his clothes,wash?? Arrange and agree on an alibi with his mother who must have instantly accepted what Luke had done and decided to cover for him.All this in ten minutes,and we know it couldn't be much longer because Luke phoned Alan Ovens at 5.40,calmly enquiring as to Jodi's whereabouts.Quite amazing,ten minutes to sort everything out before leaving for the evening.
What about option 2? Well,much the same,although he may have had slightly longer to sort things out,although remember,he would have been sitting on the wall with blood stained clothing,very risky.
Option 3? 6.35-7.00,much the same,but remember it is claimed that Corinne had started burning the clothes by 6.30.
Option 4? Very,very unlikely that Luke did not return home to secure an alibi by this time,as pointed out Jodi could have been found by then and the police could have been present at his mums house on his return home from the Abbey.
So,as I said earlier on,every prosecution scenario has problems.
Just imagine for a moment what could have been said between Luke and his mother if he returned at 5.30.
Corrine-'Oh hi Luke,far hiv you been? Luke-Well mam,I'm afraid I've jist killed Jodi,I've been plannin tae butcher her for a while noo' C-'Och ats terrible son,but I suppose these things happen.' L-'aye mam,onyway,can ye wash ma clothes,they've got some bleed on em?' C-'aye of coorse son,yell nae be needin tae tak the blame for her murder.In fact I will burn yer clothes jist tae mak sure,ok? L-'aye great ma,n mine tae tell the police that I wiz at hame hayin ma supper at the time o' the murder ok?' C-'aye of coorse laddie,now jist you awa oot in play we yir pals n'leave yir mither tae sort a'thing oot,ok?' L -'jings aye ma,great,see ye later' C-'see ya Luke,yer a braw wee laddie,am prood o'ye'.
Or what do you think was said between mother and son Steve? And at what time?
Surely you cant have an opinion of guilt or innocence until you have gone through a complete scenario taking every option into consideration?
