Whodunnit?

Today I found a dead body in the kitchen in the midst of a pile of feathers. Katy can be seen here at the scene of the crime with her best 'who me?' expression... surrounded by feathers. This makes her the main suspect...however there are two other potential suspects, Misty and Brutus - I do not have MrD on my list, he cant run fast enough to catch a bird :-) ! So these two could have been responsible for the murder, but too smart to be caught at the scene. I havent had a confession yet despite intensive questioning. Another unsolved crime. :-)
