What is a detainer in the context of custody management?

A detainer in the context of custody management refers to a formal request or document from a law enforcement agency informing another agency, typically a correctional facility or a jail, that they intend to keep an individual in custody for additional legal reasons. This is often used when an individual is already incarcerated for one offense, and another jurisdiction has charges pending against them. By placing a detainer on that individual, the agency indicates that they have a legal interest in the custody of the person until their matters are resolved.

This process ensures that the individual does not simply be released back into the community without addressing the new charges. It highlights the importance of coordination between law enforcement entities and the custody management system, ensuring that individuals remain under appropriate legal supervision while their cases are processed. This understanding is crucial for jailers in managing inmates effectively and safeguarding legal protocols.
