Days Spoiler!! don't look if you don't want to know how the killer is revealed.
From about.com
I don't know if this is true or not, but:
It is believed that it will be Marlena who injects Tony (while hospitalized from tiger attack) with the lethal dose that kills him. Unfortunately for Victor he sees the killer. With Tony dying after or during his visit Victor is then main suspect. Victor puts two and two together and realizes that Marlena is the Salem Serial Killer. Of course anyone knowing the identity of the killer gets whacked and that is exactly what happens to Victor. Celeste soon figures out what all the cryptic messages from Abe, Roman and Maggie have meant and surmise that Marlena is the killer. Shortly thereafter Celeste is killed. Somehow Hope begins to realize whom the killer is and is attacked by Marlena. Celeste's premonition comes true as John saves Hope but must kill his wife. But wait it doesn't stop there! It seems that “Marlena” has been possessed by the devil AGAIN only it isn't really Marlena its Hattie! Now Hattie is dead but the “devil” leaps from “Marlena” to John. Now the saddest part of all, a possessed John goes after Alice…. Alice and all of the deceased loved ones expel the devil, but in the process we lose our beloved matriarch of Salem.
