CSI Time @ Selby Break in at the Selby Museum. PC White arrived at the Museum where he met the Security guard. Here is what he said. • “It was about 10.30pm and I was just about to do a sweep of the museum when I heard light footsteps, I quickly turned around to see a dark figure emerging from the basement doorway. The figure seemed small and thin and started to move quickly. The figure was heading for the back exit; I started to chase after them but couldn’t keep up. They ran through the back exit setting the main alarm off. By the time I had reached the door they were gone. This was when PC Doyle arrived.”
The Crime Scene Investigators(CSI) did a sweep of the building, dusted for finger prints, shoe prints and looked for any other evidence that been left by the suspect. As they were passing PC White asked what evidence had been found, the head CSI investigator said some Foot prints, skin cells and some hair fibres were found.
