The Investigative Section functions in support of the Support Services Division. The primary goal of the Section is to provide follow-up criminal investigations leading to the identification, arrest and prosecution of suspects, recovery of property and the clearance of cases. Section personnel employ a variety of investigative techniques and teamwork to accomplish this goal.

The Investigative Section includes three (3) specialized bureaus:

  • Crimes Against Persons caseloads include Robbery/Homicide; Domestic Violence; Elder/Child Abuse;  Sex Crimes; Assaults; Weapons Violations. 
  • Crimes Against Property caseloads include Forgery/Fraud; Identity Theft; Elder Financial Abuse; Grand Theft Auto; Residential/Commercial Burglary; Grand Theft. 
  • High-Tech Crime caseloads include County, State, and Federal large asset forfeiture cases.

The complexity of modern criminality requires detectives be trained and knowledgeable in all the specific types of criminal activities in each category. Investigative Services personnel conduct all aspects of criminal investigations.

OTHER CRIMINAL ACTIVITIES HANDLED BY THE DETECTIVE BUREAU Civilian, non-sworn support personnel (a Police Service Officer) also handle a variety of matters including Misdemeanor Adult Crimes; Alhambra Municipal Code Violations; Annoying & Harassing Telephone Calls; Vandalism. 

Additional tasks include: Subpoena Service, Photo Lab Duties and Court Liaison. An assigned uniform patrol officerwill conduct an initial investigation, write a report on the crime circumstances, pertinent facts, witness statements andlist physical evidence at the scene. Cases are prioritized for investigative follow-up based on the severity and natureof the crime and the presence or absence of workable leads. Current investigative skills, techniques and technicalresources are used to identify, locate and apprehend criminal suspects, recover stolen property and provide prosecutors with criminal cases that will culminate in successful prosecutions. 


  • The S.E.U. unit is comprised of detectives assigned to specific caseloads involving all gang-related criminal activity, vice, narcotics, criminal intelligence and alcohol-related crimes and is supervised by a police sergeant. The unit works with county, state and federal law enforcement agencies.
  • Gang enforcement officers assigned to the Field Services Division work in partnership with SEU conducting monthly enforcement operations focusing on criminal gang activity, parolees, and those on active probation. One S.E.U. detective is assigned to the West Covina Police Department's Special Enforcement Team.

  • The Property Unit, staffed by a Property Clerk, annually processes on average 5,000 items of property and evidence booked into the property system. Items are logged, inventoried. Tens of thousands of pieces of property are maintained in the Property Unit. The Property Clerk is also responsible for releasing and disposing of items pursuant to applicable law.
