LGC Forensics: Digital and document forensics services

Information is stored everywhere...

As digital files on MP3 players, mobile phones, laptop computers and in-car satellite navigation systems. They can be letters, pictures, emails, or just the ringtone on your mobile. What could they tell us about someone's behaviour and movements in connection with crime?

Meanwhile, we continue to produce mountains of paper files - printed, typed or handwritten documents which contain a wealth of unseen evidence and often provide the only completely legitimate and visible evidence in criminal and civil cases.

LGC Forensics follows quality-assured, proven and reliable scientific procedures to examine and recover data from digital devices and evidence hidden in typed and handwritten documents. We are able to meet any client need by adapting our services to suit individual cases and investigations. We combine innovative and traditional methods with understanding to reveal high-quality digital and documentary evidence that will stand up in court.
