The assailant/s used 3 weapons. 1) a martial arts kendo stick. 2) a samurai sword. 3) a kitchen knife. All 3 weapons belonged to the deceased. All 3 weapons were found at the scene of the crime, along with a hammer.
Pearson was arrested a day before Duane and claimed that Duane had confessed to murder. Duane claimed he had observed Pearson hide a knife under a paving slab. (Police found this hidden knife exactly where Duane saw Pearson hiding it) but DNA fingerprints could not be found. Which, if any of these knives was it claimed to have inflicted the fatal blow that killed David Williams? Were Davids other injuries consistent with being assaulted with a hammer and kendo stick?
In this laundry bag, police found a t-shirt with 3 small spots of blood DNA, although not visible to the naked eye, it tested positive for blood DNA that matched the deceased’s.
However results of forensic/DNA testing of the t-shirt showed that the full DNA profiles of at least three other individuals – including the deceased’s – were present on the inside collar, and also the underarms of this garment.
Is it possible that the spots of blood "not visible to the naked eye", came to be there due to the vicitm sneezing whilst another was wearing the t-shirt? Is it known who the full DNA profiles match too?
How did the police know that Duane would be at the council offices that day?
How many dogs lived at David Williams home and what breed were they?
