Zacharias ran a hand through his hair, tucking his wand away as the aurors approached. Perhaps this time he might even get a chance to explain himself before he was bound and locked away. He even did his best to ignore the slight about this being the second body he was found with, it wasn't like he went looking for these things.
It did probably work in his favor that the person wasn't with him wasn't some hysterical half naked woman, but rather a somewhat respected man who even freaked out could manage to keep his wits about him. He gave the auror the basics of what had happened while the other worked to further secure the scene.
It would seem that any thoughts of immediately getting back to the office were best to be abandoned. Zacharias might be taken away bound, but both he and Anthony would have to go back to the department and likely give their official statements about what they saw. Not that there was anything to see, it was more of a finding.
