Investigation Through Arrest Phases

Communication Between Investigators and Laboratory

Investigators and laboratory personnel remain engaged in the process well after a suspect's arrest. It may be years before a case is presented to a judge or jury for the first time. A proper understanding of the roles, responsibilities and skill sets offered by investigative and laboratory personnel is essential to ensure a successful case.

Early Involvement of the Prosecutor

It is equally important that investigative and laboratory personnel remain in communication with each other and the prosecutor during the pendency of the prosecution.

The prosecutor should be involved in the investigation phase as soon as is efficiently possible. This involvement will vary depending on the size of the jurisdiction and the availability of prosecution staff.
