A murder case involves the investigation and legal proceedings surrounding the unlawful killing of a person. Law enforcement agencies, such as the police, gather evidence, interview witnesses, and identify suspects to solve the crime. The process often includes forensic analysis, which may involve DNA testing and other scientific methods to establish facts. Once a suspect is identified, the case may proceed to court, where a prosecutor presents evidence to prove the suspect's guilt. The accused has the right to defend themselves, often with the help of a defense attorney. The outcome can result in various penalties, including imprisonment or, in some jurisdictions, the death penalty.
