To examine a place vehicle or item for forensic purposes.
Additional Information
I am a METROPOLITAN POLICE crime scene examiner and thus word is used by police officers verbally and in written form on a daily basis for years. There have even been Facebook pages dedicated to the use of this word and is deemed annoying to forensic staff! Usage can be- 'Can someone please forensicate the knife for blood?' The other versions are Forensicate, as in- 'the car has been forensicated'.
