Presentation for Helen Jones

We are required to give a 20minute presentation for Helen. I have decided to give a powerpoint presentation on evidence. I am using the gate I photographed on day one of the course, as when I approached it I immediately recognised it as a possible crime scene. As can be seen the gate has been forced inwards. On closer inspection there are several evidence types present incuding paint from the offending vehicle. There are also marks on the chain linking suggesting someone has tried to cut it with bolt croppers or similar. There were no obvious tyre marks, however it is not known when this crime took place.
