El Monte is one of many cities in Los Angeles County, of the state California. It was incorporated as a city about one-hundred years ago in the year 1912. Since then, El Monte has had its view of the nearby San Gabriel Valley marred by the industrial, commercial, and residential buildings that have begun to overwhelm the city. El Monte has an enormous population size of about one hundred and thirty thousand as of the year 2010, which is two thousand less than ten years prior when the census was taken in the year 2000. Also according to the 2010 census, El Monte is number 51 on the list of the biggest cities that reside in California. El Monte is considered a great and amazing place to live, and the city has even adopted the slogan of “Welcome to Friendly El Monte”. El Monte has a historically important historical spot because it is known as “The End of the Santa Fe Trail”. El Monte also has a good historical spot as it is between the gigantic landmarks of the San Gabriel Valley, and the Rio Hondo Rivers. El Monte is sometimes mistaken to mean the mountain, but actually El Monte translates into the meadow or it can also translate into the marsh.
The city of El Monte is one of the few cities in the Los Angeles County area that does in fact have its own police department. The El Monte Police Department is run and operated by the experienced Chief of Police, Mr. Steve Schuster. Chief of Police Steve Schuster has one hundred and twenty-one sworn police officers helping him to keep the city safe.  These one hundred and twenty-one police officers make up a large percentage of the people actually employed by the City of El Monte. Who happens to to be El Montes fifth biggest employer, with about four hundred and twenty-nine total employees hired to serve the city. These police officers do not always have to act completely alone though, and sometimes call upon private investigators for help.
Surprisingly. El Monte does not have a private investigator who works through an agency that has it’s headquarters set up within the city.  It has many private investigator companies that do still act, and service the El Monte area though, mostly agencies that set their headquarters up in the big city of Los Angeles. Other cities with agencies who offer their private investigators to the city of El Monte  include the nearby cities of Fullerton, Costa Mesa, Downey, Pasadena, Claremont, and Santa Ana. The private investigators who serve the city of El Monte usually specialize in cases involving adultery, child custody, worker’s compensation, disability, or missing persons but are still able to work on cases involving a great number of other things.
So between the private investigators who serve the city of El Monte, and it’s vast number of police officers, El Monte is in very capable, lawful hands.
