Murder investigation is spelled /ˈmɜːdər ɪnˌvɛstɪˈɡeɪʃən/ in American English. The word "murder" is pronounced with the vowel sound in "fur" /ɜː/, followed by the consonant sounds "d" and "r".

Murder investigation refers to a systematic and thorough examination conducted by law enforcement agencies to determine the circumstances, facts, and perpetrators involved in a case of unlawful killing or homicide. It involves a series of steps and procedures aimed at gathering relevant evidence and establishing a viable solution to the crime.
During a murder investigation, various techniques and strategies are employed to identify, apprehend, and convict the individual(s) responsible for the victim's death. These usually include the collection of physical evidence (such as fingerprints, DNA, and weapons), interviews and interrogations of witnesses and potential suspects, reviewing surveillance footage, analyzing crime scene patterns and characteristics, and examining medical reports or autopsy results.
Furthermore, murder investigations often involve collaboration between different law enforcement departments, such as detectives, forensic experts, officers specializing in violent crimes, and legal professionals. They may also seek assistance from forensic psychologists or profilers to develop a psychological profile of the offender.
The ultimate goal of a murder investigation is to gather enough evidence to solve the crime, provide closure to the victim's family and loved ones, and uphold justice by apprehending and prosecuting the perpetrator(s) in a court of law. It is crucial that murder investigations are conducted with the utmost professionalism, diligence, and adherence to legal regulations to ensure the integrity and reliability of the gathered evidence.
The word "murder" originated from the Old English word "morðor", which was derived from the Proto-Germanic word "murþrą". Its ultimate root can be traced back to the Proto-Indo-European base "*mer-", meaning "to die".
The word "investigation" comes from the Latin word "investigatio", which means "a searching into". It is derived from the verb "investigare", which combines "in-" (meaning "into") with "vestigare" (meaning "to track or trace").
Combining these two words, "murder investigation" refers to the process of searching into or tracking a killing or unlawful act of taking someone's life.
