If the neighbor is correct the agent may have disappeared and they’re trying to find out why. One reason disappearances and suicides are well investigated is because decades ago during the cold war there was a sergeant at McDill who drove a Rolls Royce. Nobody ever questioned why a sergeant could afford a Rolls Royce. One of his jobs was to change typewriter ribbons in the classified area. He sold them to the Soviets. They only found out after he committed suicide. So, if the agent is gone, they want to know why and where.
