Forensic Science Introduction
Case report
At 6.10 pm on Friday, a community sports centre reported that its silver tournament trophy was missing from a locked display cabinet. A side window was open. The cabinet’s glass was intact, but its latch was scratched. A strip of blue fabric was caught on the latch. Investigators photographed the room before collecting anything, recorded who entered, and placed the fabric in a labelled paper bag. They found a muddy shoeprint near the window and took a cast of it. The centre’s caretaker, Alex, said they had been in the equipment shed from 5.45 to 6.20 pm. A volunteer, Dylan, said she saw a person in a dark jacket near the display at about 6.00 pm, but she could not see their face. The next day, a blue jacket with a torn cuff was found in a lost-property box. The fabric from the latch had not yet been compared with the jacket. The report does not state who took the trophy.
Read closely and reason carefully
Locard’s Exchange Principle states that when two people or objects come into contact, they can transfer traces to one another. For example, a person may leave fibres at a place or pick up material from it. Answer in complete sentences where appropriate. Use details from the case report to support your reasoning.
