School of Justice, Security and Sustainability

I am a lecturer in the Institute of Policing with a background in the investigation of serious and complex, and major crime having retired from West Midlands Police after 30 years’ service at the end of 2021.

I started in Policing in 1991 and within 5 years was working in the homicide team as a qualified detective. After several years working in homicide, in the main as a specialist intelligence operative, I moved into the cold case review team where I reviewed unsolved live homicide investigations and historic unsolved homicide and stranger rape cases.

The review work was where I developed my interest in the decision-making process within serious and major crime investigations. Being lucky enough to review, and bring to court, cases dating back as far as 1967 I have been able to access the investigative decision-making process across half a century of unsolved cases.

More recently I have worked in the Investigative training department where I was promoted to lead a team of 20 detectives delivering investigative training to new recruits, new detectives and senior detectives within the force. While in this role I completed my post graduate certificate in higher and professional education with Staffordshire University.

I joined the Institute of Policing in January 2022.
