The Investigatvie Service Division initiates investigations and handles all the follow-up and casework for incidents that require a response by patrol officers. The Division also responds to citizen and council complaints on criminal activity. The Division is staffed with detectives, a major crime task force, and specialty trained civilian personnel.


Traffic Services
The Traffic Services Unit consists of seven Motor Officers and four Parking Enforcement Officers. They are specifically responsible for enforcing the State Vehicle Code and the traffic section of the City Code. They regularly conduct special enforcement details focusing on impaired drivers, occupant protection, license verification, and speed compliance. Members of the Traffic Unit receive specialized training in traffic accident investigation and reconstruction, becoming experts in the field. These highly trained individuals make up the MAIT (Major Accident Investigation Team) that is responsible for scientifically determining the cause of fatal and major injury accidents. The Traffic Services Program is also charged with the responsibility of reducing traffic collisions through education and enforcement of the Vehicle Code. Education includes increased awareness of traffic and pedestrian safety through presentations to schools and civic groups. Close contact is maintained with City Traffic Engineering and Cal Trans to solve problems that might contribute to traffic collisions. Additionally traffic collision reports, including hit and run investigations, are reviewed by the Traffic Bureau for prosecution of drivers who cause the collision. Motorcycle officers are used in many traffic control situations due to their superior mobility. Parking Control is responsible for the enforcement of parking regulations in the City. In addition to supervising Traffic and Parking Enforcement, the Senior Parking Enforcement Officer also supervises 38 hourly Crossing Guards assigned to 24 elementary schools to ensure the safety of the students.

Burglary Unit
This unit is comprised of investigators that investigate all residential and commercial burglaries. They attend community meetings to educate the public in crime prevention. This unit is responsible for the implementation of the first Burglary Investigator's Association in the San Gabriel Valley. The Association exchanges information on crime patterns to identify suspects involved in burglaries. This is a multi-agency team effort. The unit also works closely with the local pawnshops to identify suspects who attempt to sell stolen property.

Domestic Violence
Patrol officers are required to document incidences that the actions by the parties involved constitute some type of domestic violence. Two detectives are assigned to investigate these complaints. Each detective receives 50-60 cases each month for follow-up investigation.

A victim in a domestic violence case must remember one very important thing; if there' s been a crime committed, the District Attorney will prosecute even if the victim doesn't seek prosecution.

Robbery Unit
The Robbery Unit is comprised of two investigators who have the responsibility of investigating all robberies in the City of Pomona. In addition, both investigators attend multi-agency meetings to exchange information on crime patterns, suspect information, and discuss new technology in the field of robbery investigations. This unit received $15,000 in state grant funding for new video equipment to assist with investigations. The Robbery Unit recently hosted a Robbery Prevention Seminar that was attended by Pomona business owners and managers.

Sexual Assault Detail
Two detectives are assigned to handle all sexual assaults and child abuse. A state requirement for any officer working this assignment is to complete a 40-hour training class. Each detective is assigned approximately 20 cases a month. The cases include sexual battery, physical abuse to minors, serial rapist, pornography or Internet child pornography. Because of changes in sentencing in recent years, most sexual assaults and felonies carry a minimum of a six-year prison sentence. In a recent case, a felony suspect was sentenced to over 900 years, the second longest sentence in Los Angeles County.

An additional assignment to this detail is the registration of convicted sexual assault individuals in compliance with Megan's Law. Once an individual is released from prison, he/she has a lifetime requirement to register each year with law enforcement on his/her birthday, or whenever he/she moves. Currently, Pomona has about 275 registrants, a number consistent with cities of our size.

Grand Theft Auto Detail
The Auto Theft Detail processes auto theft in-custody's (prepares cases for presentation to the district attorney's office), and conducts follow-ups on cases with workable leads. These leads may result in the investigator preparing a search warrant, arresting a suspect, recovering a stolen vehicle, and identifying a car theft ring. Investigators also conduct vehicle inspections where the public vehicle identification numbers have been removed. They also review all stolen and recovered vehicle reports for the City and conduct business inspections looking for stolen vehicles and for compliance with state and federal laws.

Homicide Detail
The Unit has the sole responsibility of investigating the untimely death of persons who are victims of homicide. These detectives work diligently on a murder case to help identify and capture the perpetrator.

Pomona homicide detectives investigate an average of 30 homicides a year. These murders include drive-by shootings, stabbings, strangulation's, and child deaths. The unit also investigates attempted murder cases, attend autopsies, and review unsolved murder cases. A homicide detective must be methodical and persistent in his approach to a death investigation. The detective has the overall responsibility of preparing a case for a criminal filing and will assist the Deputy District Attorney through the trial process.

The homicide unit is comprised of one sergeant and six detectives. Evidence technicians gather and document evidence to support the unit. On a murder investigation call-out, a team consisting of one sergeant, two detectives, and one technician respond to the crime scene to initiate an investigation. Since death usually strikes without warning, the homicide unit is subject to being on-call 24 hours per day, 7 days a week.

It has been said, "That no greater duty will ever be bestowed upon an officer then when he is entrusted to investigate the death of another human being."

Major Narcotics Unit
The Major Narcotics Unit investigates major narcotics trafficking in and around the City of Pomona. The unit places emphasis on invetigations which directly involve the flow of large amounts of narcotics into our community.

The unit consits of one sergeant, one corporal and four patrol officers who conduct covert surveillance of narcotic traffickers and gather intelligence which is used by the law enforcement community. The unit routinely works with and assists other law enforcement agencies such as the FBI, the Drug Enforcement Administration, and the California Department of Justice.

Since the units inception several years ago, it has been responsible for the confiscation of hundreds of pounds of illegal narcotics and millions of dollars in U. S. currency related to the illegal trafficking of narcotics.

Gang Violence Suppression Unit/Vice
Their responsibilities include the tracking of street gang activity, contacting individual members and associates of these gangs, and follow up on the investigation of gang-related crimes.

Another duty of the unit is the maintenance of records, which are used by the "Cal-Gangs" state wide gang database. This data is collected from reports, field interviews, and initiating contacts. Gang investigators are also the "experts" for the department in regard to street gangs and testifying in court on gang related matters.

As part of gang investigations, investigators prepare gang association warrants; targeting members of specific gangs that are involved in a particular crime. The Unit also provides assistance to other agencies investigating gang members from the City of Pomona.
