Commander John San Agustin's career with the El Paso County Sheriff's Office began in 1997 when he was asked to volunteer his time and expertise as a Crime Multimedia Specialist in the Staskiewicz/Carpenter homicide investigation; a very complex murder of a 15 year old girl and an adult male. John was an electrical engineer at the time working in the private sector. John's contributions to this case led to a successful prosecution and the value of his specialized skill set in reconstructing crime scenes through multimedia was an integral part of the courtroom evidence presentation. As a result, he was hired by the El Paso County Sheriff's Office in January 1998 to work in the Investigations Division as a Crime Multimedia Specialist. John has been involved for the last 16 years with most of the death investigations in the El Paso County Sheriff's Office jurisdiction analyzing and investigating each case to recreate the events that led up to the death.
John has also provided many courses of instruction in every El Paso County Sheriff's Office Basic Law Enforcement Academy and Citizens Academy since 1998. In addition, he has been an adjunct instructor for the past nine years at the University of Colorado at Colorado Springs in teaching a variety of classes related to forensic science. He is also a volunteer instructor with local junior high and high school students who have an interest in the criminal justice field and forensic science. Commander San Agustin is also an arrest control instructor.
Commander San Agustin has testified before the Colorado House Judiciary Committee on House Bill 06-1092, changing the possession of child pornography from a misdemeanor to a felony. He has assisted in developing the Local Interagency Methamphetamine Identity Theft (LIMIT) Task Force for the 4th Judicial District Attorney and is court qualified on computer forensics at the state and federal levels.
