The Bureau of Criminal Investigations (BCI) oversees all felony-level investigations. These incidents may include items like drug investigations, felony-level assaults, untimely deaths, homicides, burglaries, armed robberies, forgeries, sexual assaults, child abuse, child abductions, registering of sex offenders, felony-level DUI, and fatal motor vehicle collisions. They also assist patrol officers with investigations involving more resources/time available to a Patrol Officer during his/her shift.
BCI is also responsible for the handling and processing of evidence, to ensure that this evidence is secured, preserved, and stored in a sound manner; all the while, maintaining a chain of custody necessary for court proceedings. Often, detectives transport evidence to the New Hampshire State Lab in Concord, NH, and work towards addressing any issues lab technicians may have.
Given their responsibilities and opportunity to specialize in certain areas, detectives are able to sharpen their skills in particular areas, like crime scenes (to include latent fingerprints & DNA), interviews, and electronic evidence found within computers and cellular telephones. With that, they often develop and present training on certain subjects to other members of the department.
BCI also develops, implements, and conducts public informational programs in crime prevention, child safety, and other public interests.
