In investigating homicide cases, there are techniques that officers can employ. First, they can join the investigations as soon as a crime is known. It also helps to gather evidence from the crime scene such as hair strands, blood sample, and fingerprints. Additionally, investigators can join others in interviewing possible suspects and preparing search warrants (Reese, 2006).
Homicide refers to killing a human being intentionally by another person (Ulster County Information Services, 2006). There are four types of homicide, which depend on the circumstances and facts. First, the first degree murder. It is an intentional killing of a human being (“RS 14:30, n.d.). The murderer can face up to 25 years to life imprisonment or death penalty (The Ferragut Law Firm, 2008). The next type of homicide is second degree murder. This type of murder is about the “unlawful” killing of a person and the murderer can face imprisonment not exceeding life (Edelstein, 2008). It is different from the first degree murder because it is premeditated (Montaldo, 2009). Another type of homicide is manslaughter, which refers to killing of a person without the intent (Roach and Friedland, 2004, p.329). The other type of homicide is negligent homicide. This refers to the killing of a person due to negligent conduct (Ulster County Information Services, 2006).
Homicide is different from suicide in that the former is about all killing regardless of how a person may be killed (Roach and Friedland, 2004, p.263). Suicide, on the other hand, is about a person deliberately killing himself (Ballas, 2008).
In crimes, investigators gather evidence which would pinpoint the killer, the intent, the time, and other information. Dead people can no longer talk, but the body can provide investigators with evidence. For instance, the blood can be documented, collected and preserved. Blood evidence can determine the connection between the dead person and a criminal act (Schiro, n.d.).
Modus operandi means method of operating. This indicates the manner “in which a crime has been committed.” This is important in death operations so that investigators can understand how the criminal committed the crime. Moreover, it is said that modus operandi can link unsolved cases. Investigators can also find out about the identification of the criminal by comparing the modus operandi with the ones in unsolved cases. They can also find leads when they have accumulated information on modus operandi (Turvey, 2002, p.229).
