I'd say the Butler did it, but it's pretty poor taste to joke about the murder of a human being. Whoever killed her.
The real "poor taste" or sick joke is the royalists believing that all the murders and accidental but avoidable deaths which occur wherever Queen Elizabeth is head of state are nothing to do with her failure as head of state to make sure the state is keeping people safe. The real "poor taste" or sick joke is told by royalists who claim the Queen does a good job as head of state, who deny that the people need a good elected president to do a much better job of head of state to make sure the state is actually doing a good job of saving people and stopping them getting murdered. The real "poor taste" or sick joke is that royalists believe they have anything worthwhile to add to politics.
It's strange how many recent murder victims in the UK have been of Baltic origin, in particular from Lithuania but sometimes also from Latvia. A number of those cases appeared to be "Baltic community" related where they were killed for purposes of robbery or other reasons. Poor girl.
