Forensic Science Lecture 29: Investigation Of Suicide ✓ Solved
Forensic Science Lecture 29 Investigation of Suicide
Forensic Science Lecture 29 covers the investigation of suicide, including demographic information about the decedent and the informant, the specifics of the scene where the body was found, details about the body itself, the history leading up to the death, and the personal history of the decedent. The discussion involves gathering evidence to piece together the events preceding the suicide.
Demographic Information
Informant information should be collected, including the name of the person reporting the case along with the date and time. Detailed decedent information must include the name, date of birth, age, sex, marital status, social security number, address, and phone number. Identification information on how the decedent was identified should also be noted. Next of kin information should include the name and relationship to the decedent, along with their contact details and the date and time they were notified.
Death Event Information
It’s crucial to document the circumstances surrounding the death event, such as whether the body was found or witnessed, the date, time, and location where the body was found, and who discovered it. The last seen alive details, including the date, time, and location, alongside the name of the person last with the decedent, should be noted. Information about the injury, such as the date, time, and location, along with the name of the physician and the date of the last visit must also be recorded.
The Scene
The general scene description should classify the setting as urban or rural, and specify whether it’s indoors or outdoors. A specific description of the scene is necessary, focusing on the immediate location where the body was found, including the condition of the room or area, any vehicles, and other relevant details. Associate evidence that can help estimate the time of death, such as mail or newspapers, should be considered along with their delivery times. Observations regarding the lights or television status and the state of food and dishes can contribute valuable insights.
The Body
Details regarding the body location must specify whether it was on the floor, in bed, etc., along with a description of the body’s position and posture relative to the scene. Information on the clothing worn, signs of rigor mortis, livor mortis, ambient temperature, body temperature, and any post-mortem changes should be included. Initial examinations of injuries, presence of purge, and other body artifacts must be documented.
The History
Investigate what circumstances led to the body being found, including the last documented activity of the decedent. Gather the medical history of the decedent, addressing current medical problems, mental health issues, treatments, and medications. Furthermore, personal history regarding any recent changes in the decedent's life, including relationships, health, and occupational history, should be assessed.
Evidence of Intent
Scars from previous attempts, tattoos reflecting a fascination with death, and any recent purchase of weapons or changes in personal habits are critical. Family denial statements should be noted, as they provide insight into the family's view of the decedent’s state of mind prior to the event.
Alteration of Scene
Be aware of any possible scene alterations, such as destroyed notes, removed drugs, changes in clothing, or movement of the body, as these can impact the investigation’s findings.
Specific Case Example
Referencing Forensic Science Lecture 30, a specific suicide lab scenario is discussed. Details about a 911 call made at 3 am on July 4th reporting a suicide led to an investigation of a case where the decedent was found in a tub at an address in Queens, NY. Key questions arise regarding whether the decedent drowned, with considerations given to physical evidence such as towels, soap, and clothing found at the scene.
Conclusion
Understanding the multifaceted aspects of a suicide investigation allows investigators to approach each case comprehensively, ensuring all evidence is collected and analyzed thoroughly.
