History of Overland Security Services 


Bruno J. Zemaitis founded this company in 1947, by purchasing the Merchant’s Patrol Service from then, Santa Maria Police Captain, Frank McCaslin. In addition to a down payment, the balance owed was paid in the form of a handshake loan from Bank of America, in Santa Maria. Over the next 57 years, Mr. Zemaitis renamed the company “Overland Investigation Bureau” and built it into a staple of the Central Coast.

During his ownership and due to his presence between the Five Cities area and Santa Maria, county sheriffs in both Santa Barbara and San Luis Obispo Counties deputized Mr. Zemaitis. During that time, he was actively involved in investigating both minor and major crime throughout this area.

He was involved in the 1950s Wray Murder Case, in Santa Maria and the death of Betty Short, AKA the Black Dahlia; murdered in Los Angeles in 1947. Betty Short had worked for a time at Camp Cooke, now Vandenberg AFB, during WWII. Her murder remains unsolved to this day and it was thought that someone in Santa Maria may have been involved in her death.

During the 1960s, Overland was instrumental in providing security for Pacific Telephone Company during a long and contentious labor strike. Due in no small part to the efforts of Overland; telephone service in this area remained intact. In 1964, Mr. Zemaitis attended night school at Long Beach College, in the study and operation of the Polygraph Lie Detector. Mr. Zemaitis was one of the first non-law enforcement individuals to receive this training in California. Throughout his life, he continued to improve his knowledge of the law and crime prevention.

During the 1980s through the 1990s, Mr. Zemaitis and his able assistant, his wife, Beth, continued to operate Overland in providing security and peace of mind to business and industry in San Luis Obispo and Santa Barbara Counties.

In 1991, Mr. Zemaitis son, Edward, returned to the city of his birth to assist his parents in the operation and management of Overland. Edward’s background included business management, construction, real estate sales and property management. Edward is the middle son, and one of four brothers and sisters.

Edward Zemaitis efforts resulted in expansion of Overland’s service area, improved accountability and increased training for all uniformed personnel. Due to his efforts, Overland can proudly state that our personnel are among the best in our industry.

Upon the passing of Mr. Bruno Zemaitis in 2004, Edward purchased the business from the estate and continued to offer these same services under the namestyle of Overland Security Services, LLC. As technology has changed, so has the service offerings of Overland with increased use of computer, video and remote surveillance capabilities.

As of 2014 Overland has offered superior service at competitive rates for 67 years under one family management and ownership.
