Which agency is involved in pursuing criminal prosecutions in the county?

The District Attorney is the agency responsible for pursuing criminal prosecutions in the county. This role includes representing the government in prosecuting cases against individuals who are accused of criminal offenses. The District Attorney's office investigates crime, decides which cases to bring to trial, and handles all legal proceedings related to those cases, ensuring that justice is served in accordance with the law.

Other agencies mentioned, such as the Placentia Police and Sheriff - Coroner, primarily focus on law enforcement and public safety, including responding to incidents, enforcing laws, and conducting investigations, but they do not have the authority to prosecute cases in a court of law. County Animal Control is tasked with managing animal-related issues and enforcing laws related to animals, but it does not engage in criminal prosecutions either. Thus, the District Attorney plays a crucial role as the prosecutorial authority in the criminal justice system at the county level.
