When a death occurs suddenly, unexpectedly, and from unnatural or unknown causes, a forensic pathologist has a duty to gather and analyze evidence to determine if the victim died from a previously undiagnosed illness or infection. or a homicide, suicide or accident (Lurigio, 2009). When we consider suicide as a probable cause of death, we are looking at intentionally committing suicide through one's own efforts or with the help of others (Sever, 2009). A medical examiner's definition of manner of death as suicide is based on a series of factors that rule out natural causes of death, homicide, and accident (Geberth, 2013, p.55). The cause of death is also determined by the medical examiner in conjunction with the crime scene investigator; however, this can only be determined after a thorough investigation has been concluded. Therefore, in the complex process of a death investigation, several errors must be avoided, which are discussed in Geberth's article, Seven Mistakes in a Suicide Investigation (2013). Errors made during a death investigation affect the integrity of evidence when determining the cause of death and its admissibility in a court of law. Geberth (2013) refers to his book Practical Homicide Investigation in which he writes: “All death investigations should be conducted as homicide investigations. until the facts prove otherwise. Failure to treat suicide as a homicide investigation is a significant error” (p. 55). Going to a crime scene assuming the death was the result of suicide can lead to errors in the investigation and erroneous conclusions as to the cause of death. What appears to be suicide may actually be homicide or an accident. Geberth (... middle of article ...... survivors and any of these individuals can taint the process by providing "biased" memories. The most often cited limitation or weakness of psychological autopsies is the absence of any standardized procedures for carrying them out (Roberts & Baker, 2009, Psychological Autopsy, section Limitations of Psychological Autopsies, para.2). Although psychologists have developed a standardized guide with twenty-six categories to help. investigators to perform psychological autopsies, not all categories presented are applicable to every case or are considered by any psychologist conducting a psychological autopsy (Roberts & Baker, 2009, Psychological Autopsy, Limitations of Psychological Autopsies section, para.2, Westveer, Dibble, and Clemente (2008) question its validity and reliability because the accuracy of the equivocal death analysis has not been empirically studied.
