A homicide investigation is a systematic process conducted by law enforcement to determine the circumstances surrounding a death caused by unlawful actions. Investigators gather evidence, interview witnesses, and analyze forensic data to identify potential suspects and establish a timeline of events. The investigation often involves various specialists, including crime scene analysts, forensic scientists, and detectives. They work together to piece together the events leading to the death, aiming to uncover motives and gather enough evidence to support legal action against the perpetrator.
