That sounds good and valiant, but you are assuming a lot. The defendant said he was being robbed, not assaulted, nor did he say a family member was attacked and he rushed in to defend them. Two different scenarios. Defending your family means escalating a simple robbery to a much more dangerous situation. The circumstances and method of killing in particular suggest there could be more to the story. The weapon in question was a knife. If the robbery was thwarted , do you subdue the assailant and take the knife, or proceed to strangle them past the point of consciousness and even to death? This may have been a rage induced reaction to something other than robbery. Many robberies and crimes against tourists are crimes of “ opportunity”. What robber sees confronting an entire family in their room at a luxury resort where they are employed ( during their own work shift ) as a golden opportunity to pull off a heist ? Also, this happened in Anguilla, not say, Florida. What does the law say about what was done in this circumstance? There is much yet to be known in this bizarre case.
