Our reading
An editorial interpretation.
The speaker announces an inspector’s death, stresses that it was murder, and then adds that someone is responsible. That final point is already implied by murder, giving the urgent announcement an unintentionally comic redundancy. The emphatic delivery makes an obvious conclusion sound like a revelation.
