Crime presentation tomorrow, need ideas to make it more interesting?

[LittleMiss]

For a school assignment tomorrow I have to do a crime oral presentation. I am the detective solving the crime but when ever I practice it it is very boring. I need ideas to make it better. For a costume I am wearing a business shirt and tie and for props i have a newspaper clipping and a map of the criminal's route. Any ideas to make it more exciting to watch, eg hand gestures, props, costume, etc would be greatly appreciated
Thanks
