World War I

During World War I, national security became a great concern, particularly in border states like New Mexico. The mounted police were reactivated and kept the border with Mexico secure, as well as provided general law enforcement services. For the next several years, the mounted police gained quite a reputation as an effective and professional police force, much to the disdain of the state's lawbreakers, who often had strong political ties in Santa Fe. Finally, on February 15, 1921, almost sixteen years after its inception, the New Mexico Mounted Police was abolished. In 1937, it was resurrected once again as a volunteer police organization. In 1941, New Mexico Governor John E. Miles made the volunteer police organization an official state law enforcement agency as it stands today called the New Mexico Mounted Patrol.^[6]

New Mexico Motor Patrol

The advent of the automobile again highlighted the need for a statewide law enforcement agency. No other police force had jurisdictional authority to enforce laws throughout the state. In 1933, the New Mexico Motor Patrol was established, primarily to enforce traffic laws. The patrol had a civilian oversight board consisting of Governor Arthur Seligman, Attorney General E.K. Neumann, and Highway Engineer Glenn D. Macy. The state of Texas had recently created their own motor patrol, and they detailed Captain Homer Garrison to conduct the first New Mexico Motor Patrol recruit school at St. Michael's College in Santa Fe. 135 men applied for the school, eighteen were selected to attend, and ten were finally chosen and commissioned as the first motor patrol officers. Each officer was issued a Harley Davidson motorcycle with siren, red light, and other accessories. One of the ten graduates, Earl Irish, was appointed as the Chief and was given a monthly salary of $150; Patrolmen made $125 monthly. Officers were allowed $10 per month to maintain their uniforms.

The Motor Patrol proved to be a great success and within a few months of its existence, had generated more than enough revenue to fund itself. A radio broadcasting system was set up that depended on a commercial radio station, KOB, in Albuquerque. Every week, officers would wire law enforcement matters to be disseminated to the chief in Santa Fe, who would see that KOB broadcast the information twice each day, except Sunday. In this way, motor patrol officers communicated information to each other such as descriptions of wanted suspects and stolen goods.

New Mexico State Police

By 1935, the need to expand the authority and responsibility of the motor patrol was widely recognized. The Twelfth State Legislature changed the name of the organization to the New Mexico State Police and gave its officers full police powers to enforce all laws of the state and complete statewide jurisdiction. The authorized strength was raised to 30 officers; the ranks of sergeant, lieutenant, and captain were added; and salaries were increased. The uniform adopted in 1936 is still in use today, with the exception of the riding breeches and boots favored by motorcycle officers.

Districts

For operational purposes, the State Police divide New Mexico into 12 distinct Districts. Each district has a main office with a commanding officer who oversees day-to-day operations.

• District 1, Santa Fe
• District 2, Las Vegas
• District 3, Roswell
• District 4, Las Cruces
• District 5, Albuquerque
• District 6, Gallup
• District 7, Española
• District 8, Alamogordo
• District 9, Clovis
• District 10, Farmington
• District 11, Socorro
• District 12, Deming

Senate Bill 95 DPS Reorganization Bill

On July 1, 2015, the Motor Transportation Police Division (MTD) and the Special Investigation Division (SID) were merged within the State Police Division per the legislative action. Officers and Agents are now commissioned as New Mexico State Police officers and were removed from the state's employee classified system into the exempt system. The State Police is currently in the process to figure the most efficient and fiscally responsible way to implement uniform, vehicle and policy changes for all commissioned officers. As of November 2015, the decision to change all DPS vehicles and uniforms to match the current State Police identity was issued by the chief. Larger districts such as Albuquerque and Las Cruces will see cars, uniforms and badges issued out to the field first.

As of early 2017 all uniforms, badges and most vehicles (older higher mileage units being phased out) have been replaced with the traditional New Mexico State Police identity.
