Our Mission

The City of Vallejo Police Department’s Detective Division will properly evaluate reported violent felony crimes within the City of Vallejo. Detectives will determine the presence of sufficient information to warrant further investigation. 

Crimes will be investigated with professionalism and tenacity, giving due consideration to the rights of victims and suspects alike. Victims will be provided information concerning the status of their cases as time permits. 

Detectives will assist other law enforcement agencies towards the common goal of suppression of crime in Vallejo and other surrounding communities. 

Detective Division Case Assignment Procedures 

The Detective Division is responsible for follow-up investigation of violent felony crimes reported to the Vallejo Police Department. 

The cases are evaluated for solvability by the Detective Division Supervisor. If a case has a good chance of being solved, the case is assigned to a detective. Whether a case can be solved is determined by the existence of investigational leads. These leads must indicate the potential for successful arrest and conviction. Since police resources are limited, it is not effective or practical to devote investigational resources to cases with little chance of a successful resolution. 

Common examples of investigational leads include whether a suspect is known by a victim, existence of fingerprints, existence of a surveillance photo, or other substantial information which may lead to the identification of a suspect. 

If sufficient investigational leads do not exist, the case may be suspended. If new information develops in the future, a case can be reopened and assigned to a detective. 

Detectives may become involved with the investigation of other incidents, which could pose substantial risk to the lives of our Vallejo citizens. Such cases may include some missing persons, sex registrant management, and other suspicious activity that may result in a criminal offense.
