Policing Fellows

Lieutenant Travis Martinez

Travis Martinez is currently a lieutenant with the Redlands Police Department overseeing the Special Operations Bureau. During the fiscal crisis of 2011, Lt. Martinez sought an innovative and affordable strategy to address crime trends occurring in the community.  RPD began deploying specialized GPS technology to apprehend those that were driving up the crime rates.  Experiencing immediate results with arrests for crimes such as vehicle burglary, armed robbery, and commercial burglary, Lt. Martinez focused his California Command College project on how GPS technology could be used to address all crime trends and wrote an article on the Redlands program that was published in the January 2014 edition of the Police Chief Magazine.  The facilitators of Command College selected Lt. Martinez’s project to be presented at the Command College graduation attended by several law enforcement executives from across California.

Lt. Martinez holds a Master’s Degree in Public Administration and has presented at several international, national, and state conferences on how to address crime trends utilizing GPS tracking devices and taught POST approved classes on the topic in several states. He oversaw the implementation of the GPS tracking program at RPD which has led to the apprehension of 152 suspects for various types of crime including robbery, bike theft, vehicle burglary, residential burglary, commercial burglary, metal theft, wire theft, credit card skimming, cemetery theft, vending machine theft, constructions site theft, and laptop theft. As a result of the program, RPD has recovered over $200,000 in stolen property including two recent cases where detectives were able to locate over $75,000 in stolen property taken from 11 different residential burglaries in the Inland Empire.

Lt. Martinez created the “While You’re Away Program” in which Redlands citizens can pick up a laptop that has a GPS tracking device embedded in it and place it on their kitchen table to help provide the resident with 24/7 electronic stake-out protection while the resident is away on vacation.  The program was recently highlighted in the February 2014 COPS Community Policing E-Newsletter and is now being replicated by other police departments throughout the United States.  Throughout his career, he has received numerous awards, most recently being named the 2012 City of Redlands Safety Manager of the Year.

He then conducted checks on inter-rater reliability to demonstrate the feasibility of reliably coding factors related to constitutionality from administrative records of police use of force.
