THE POLICE THINK I HAVE SOMETHING TO DO WITH MY WIFE'S DISAPPEARANCE! HELP!

My wife Christine has been missing for 48 hours, so I filed a missing person's report. An officer came by this morning to ask a few questions, and now my house is swarming with police! What do I do?
  1. The police found blood on my wood-chopping axe in the shed!
    I've only used it to chop wood! Maybe someone snuck in there and used it?
  2. The window was broken with my favorite bowling ball, Knockout!
    They could only find my fingerprints on it!
  3. Detectives found a to-scale, illustrated diagram in the garage titled "I'm Dad and here's how I killed my wife, Christine"!
    I don't know where it came from! I swear I didn't make it! I'm not the crafty type!
  4. I don't know how any of this happened! Please, someone help me figure this all out!
