Dr. Peter Gregory
Dr. Gregory joined the Forensic Science Service in 1964 and remained there for 34 years until 1998. He worked as a biology case reporting officer, mainly involved with offences against the person cases.
The main evidence types include body fluids (blood, semen and saliva), hairs and fibres; also, less common evidence types include damage assessment (e.g. torn clothing and knife cuts), and the examination of wood, other plant material and soil.
