The Crown alleged that defendant was involved in the dousing in pure sulphuric acid of a sleeping man in a love triangle gone wrong. The prosecution could show the defendant had purchased the acid, tested its effectiveness on raw meat, talked to individuals about a planned acid attack, was very jealous of the victim (his love rival) and was present at the scene of the attack albeit banned from attending there by a Restraining Order. The defendant was acquitted, his co-defendant girlfriend is now serving life imprisonment.
