Why Mesa PD?

Every Police Department has their own unique characteristics and advantages; even if they are only a few miles apart.  The Mesa Police Department offers state-of-the-art facilities in addition to other forms of cutting-edge technology that make protecting our community more efficient for our team.


State-of-the-Art Facilities

Mesa PD runs the most thorough, in-depth academy in the state of Arizona; one used and respected by other state agencies. Our dispatch center dispatches regionally and nationally acclaimed crime lab that has been opened up to our neighboring agencies. The Mesa PD also owns our own jail.  



Fusion is a collaborative group focused on cross-agency information. The Police Chiefs of the Gilbert Police Department, Salt River Police Department, Chandler Police Department, Scottsdale Police Department, Tempe Police Department, Apache Junction Police Department, the U.S. Marshals, and Mesa PD come together to disseminate information to better serve the entire Arizona community. The Mesa PD is proud to be the host of this dynamic group.   


New Hire Mentor Program

The Mesa Police Department believes the one of the best ways to learn is from each other. Our New Hire Mentor Program allows professional relationships to develop between new and more seasoned members of the department to strengthen the skills learned during training. Each new team member is assigned a mentor to serve as an advisor, supporter, contact person and resource for general information to assist with the successful transition into a new work environment. 


Latent Print Unit

The Latent Print Unit performs
scientific examinations in the area
of friction ridge analysis, including
the comparison of latent finger
and palm prints to known subjects'
prints. Various powders, chemicals,
and illumination techniques are
used to process evidence for latent
prints. Latent prints are searched
in a computer database known as
the Arizona Automated Fingerprint
Identification System (AZAFIS), which
enables unidentified latent prints to
be compared with approximately two
million finger and palm print records from known individuals within the database. The Latent Print Examiners are responsible for processing major crime scenes, providing expert witness testimony regarding their findings in courts throughout the state, and instructing law enforcement personnel.


Controlled Substances Unit

The Controlled Substances Unit examines evidence for
the presence of controlled substances including but not limited to marijuana, cocaine, cocaine
base (crack), methamphetamine,
and heroin. Unit members also provide expert courtroom testimony regarding the identification of controlled substances as well as training and oversight to officers and other department members who perform preliminary drug testing in the field.


Toxicology Unit

The Toxicology Unit performs blood alcohol analyses, urine drug screening and confirmations, and supports the preliminary breath alcohol testingas well as the Drug Recognition Examiner programs. Toxicology Unit members also assist officers during alcohol workshops. Various analytical techniques are used to determine
the concentration of drugs in blood and urine samples. Members of this unit provide expert witness testimony often, regarding DUI and other cases.


Firearms Unit

The Firearms Unit conducts examinations of firearms and tool mark evidence to determine if a firearm or tool was used in a crime. Suspected firearms or tools are compared to evidence cartridge cases, bullets, or tool marks using a comparison microscope. Other examinations performed include firearms function testing, distance determinations, ejection pattern

testing, obliterated serial number restorations, and shooting incident reconstructions. In addition, examiners enter fired cartridge cases and bullets into the National Integrated Ballistic Information Network (NIBIN), which contains images of fired cartridge cases and bullets from crime scenes, as well as test fires from guns used in crimes. When new images are entered into the system, images are searched in the database for a match. Members of this unit also testify in court.


Biology Unit

The Biology Unit examines evidence for the presence of biological substances and analyzes a sample to obtain a DNA profile. The Biology Unit compares
known profiles from victims and/
or suspects to evidentiary sample
profiles for inclusion or exclusion in
a case. The profiles are then entered
into the Combined DNA Index System
(CaDIS). CODIS compares evidence
from one crime scene to another
as well as arrestee and convicted
offender profiles nationwide. The
Biology unit also conducts bloodstain
pattern analysis in the lab and at
crime scenes. Members of this unit
provide expert witness testimony
in court regarding their findings in
the areas of Serology (body fluid
identification), DNA, and Bloodstain
Pattern Analysis.


Fingerprint Identification Unit

The Fingerprint Identification Unit processes suspect, juvenile, and applicant fingerprints through the Arizona Automated Fingerprint Identification System (AZAFIS) to search against prior records in order to provide an identification. They also perform inked print comparisons, maintain fingerprint records, and testify in identification hearings in court.


Photo Laboratory Unit

The Photo Laboratory Unit produces digital, color, and black and white reprints for Police Department members; city, county, and federal agencies; and public records requests. In addition to processing film for investigations, the Photo Lab provides various forensic and public relations photographic services; manages the negative and digital photo files; and provides photographic training to Forensic Services personnel.
