In most instances, crimes must be reported to the County of El Dorado Sheriff’s Department, Placerville Police Department, South Lake Tahoe Police Department, or the California Highway Patrol.
Once the case is filed, the District Attorney Investigators assist the Prosecutors in preparing the case for trial by conducting interviews, interrogations, processing evidence, and preparing reports. District Attorney Investigators are also involved in the initial investigation phases of parental abductions, insurance fraud, consumer fraud, statutory rape, family support matters and officer-involved shootings.

While with Amador County, he attended the Sacramento County Sheriff’s Academy and subsequently started his law enforcement career performing patrol duties for the Amador County Sheriff’s Office and becoming a District Attorney Investigator.
In 2007, Richard Pesce transferred to the El Dorado County District Attorney’s Office where he was initially assigned to investigate High Technology Crimes. He was later assigned to investigate substantial and special cases as determined by the District Attorney. Richard Pesce has investigated and helped successfully prosecute many homicides and significant cases which include: Phillip and Nancy Garrido for the kidnap and sexual assault of Jaycee Dugard; David Zanon, for the first-degree murder of CHP Officer Scott Russell, resulting in a death sentence; Charles Bailey for the kidnap and brutal first-degree murder of his 2-year-old son; Morris Greenberg for the first-degree murder of Anthony Dumont; and school janitor John Luebbers for the first-degree murder of Principal Sam LaCara while school was in session.
