Our main character's detective badge was our first thought fore a potential prop. Though it may be a part of his costume at first, we figured it would become a prop when he uses it to open doors. The same could apply to the mask the murderer wears, we threw around ideas for dramatic, significant shots of the murderer putting on and taking off the mask, in which instance it would be prop The murder weapon, a knife, was something we have previously discussed. We decided on a knife rather than a gun or a sword as it makes for a much more personal murder.
