Season 3[]

Dr. Ennis first appears in the Morgue giving a post mortem report to Holmes, Detective Bell and Kitty Winter on a John Doe. She reports that he's a homicide victim and was killed by a blow to the head and ignores Holmes when he says he already pointed this out. She also reports that all the other bodily injuries were post mortem including his ripped off hand and, that he has DNA under his finger nails which hasn't been identified.[1]

Holmes points out that a multi-purpose tool that is an ax, crowbar and hammer was used to kill Bader.[2] Grannis reports that Ian Walker died of asphyxiation when a chloroformed rag was held to his face too long.
