(the lad also spoke of the distinctive badges of the German national flag on the sleeves (Andrina Bryson also alluded to these).
If Luke Mitchell is being pictured wearing a parka in the press alongside coverage saying he's the only suspect then the police interview locals of course they'll find some that say he had a parka.
Just like they had numerous witnesses to say he had a German army shirt.
Andrina Bryson did not allude to German flags you really need to put a source for that claim.
According to Sandra Lean AB maintained throughout her time on the stand that it was not a parka that she seen and she did not identify Luke Mitchell despite the press coverage. The first mention of a parka in the case files is from RW when she said 'it could have been a parka'.
Before this the police were questioning Luke Mitchell about a German army shirt that they already had in their possession.
Even if you were to believe he had a parka before the murder which he didn't, how would a parka stop blood transfer and keep him clean head to toe? How does a Parka stop Luke's DNA transferring to Jodi?
Where's the time to give it to his mum to burn then clean up while staying dirty? It makes no sense when you look at the parka evidence for what it is.
