Who is framing EJ for Stefano's murder?
Will; he's tired of being controlled by EJ
Ian; he despises the powerful DiMera heir.
Stefano; he's still alive and hatching a secret plan.
Kate; she wants sole control of Stefano's estate.
Nicole; if EJ's in jail, he won't be able to come after their child.
John; he's desperate to bring down his evil nephew.

I think it is John. OR, it could be Will and John working together.

Part of me thinks that Will may be in love with EJ or have an crush on him or something.

Disappointed EJ and Sami didn't at least kiss today.

I'm sure that Stephano is dead (I think?) but I don't think the person we see in black is Will or John. Could it be that one of Stephano minions is prowling around leaving evidence? I can not decide if it's because he's working under Stephano's directions or he's the killer.

Ian still seems to be suspect in my mind.

Will has gotten much too cocky - he's going to be in real trouble soon.

Ian flashes back to planting the bullets and gloves in EJ's apartment.

I have always had a sneaking suspicion that Ian killed Stefano, and I think he is framing EJ, especially after today's episode.
