Could someone please help me?!?

I'm going crazy here. I know I should wait till the shows are done but I can't.. On tonights episode of pretty little liars when melissa said she didn't leave the house at all and spencer went into the closet and found the saunagram picture in melissa's wet raincoat and muddy boots.. She obviously went out but not far! Everyone keeps saying ian is dead because well duh he was hunged to death but still part of me thinks he is still alive cuz melissa took that baby picture and showed it to someone... Could someone help me figure it out please!
