Patricia (Trish) Larrigan Operational Forensic Manager, Metropolitan Police Service.
1984 - Joined the Fingerprint Bureau at New Scotland Yard as a trainee Fingerprint Officer. My career has seen me achieve Fingerprint Expert status, be trained in crime scene examination, serve 5 years with Counter Terrorism and then become a Crime Scene Manager (now OFM) when the role was civilianised. I was one of the first CSMs when the role was officially created in 2001 and the role has been developed by the people doing it – there was no playbook!
In the 25 years since becoming and OFM, I have taken part in the investigation into hundreds of Homicides, Unexpected Deaths and many other serious crime incidents.
