ABMDI - American Board of Medicolegal Death Investigators Investigating Infant and Child Deaths Questions and Answers 1 — Questions and Answers
Question 1: An investigator is called to the scene of a 4-month-old infant found unresponsive by a parent. To best document the infant's position and the specific circumstances of the sleep environment as they were found, which specialized technique is recommended by the CDC and the National Association of Medical Examiners?
- Relying solely on the parent's verbal description.
- Taking photographs of the crib after the bedding has been removed.
- Using a doll to re-enact the infant's placed and found positions. (Correct answer)
- Measuring the room's dimensions and creating a hand-drawn sketch.
Correct answer: Using a doll to re-enact the infant's placed and found positions.
Using a doll for re-enactment is a standard and critical procedure in a Sudden Unexplained Infant Death (SUID) investigation. It allows the caregiver who found the infant to demonstrate the exact position and circumstances, which is vital for the pathologist to understand potential mechanisms of death like asphyxia. This visual documentation is more accurate and objective than verbal descriptions alone.
Question 2: A medicolegal death investigator is examining a 2-year-old child and observes a series of well-demarcated bruises on the child's back that resemble the shape of a looped electrical cord. In the investigative report, this finding should be documented as:
- Postmortem lividity.
- A patterned injury. (Correct answer)
- Contusions of unknown origin.
- Senile purpura.
Correct answer: A patterned injury.
A patterned injury is an injury that has a specific shape or pattern suggesting that a particular object or weapon was used to inflict it. Describing the bruises as a patterned injury resembling a looped cord is the most accurate and objective documentation, providing crucial information for the forensic pathologist and law enforcement about potential non-accidental trauma.
Question 3: Which of the following is required before a medical examiner or coroner can certify the cause of death as Sudden Infant Death Syndrome (SIDS)?
- The infant must be between 6 and 12 months of age.
- The parents must report the infant was sleeping in a crib.
- An unsafe sleep environment must be documented at the scene.
- A thorough investigation, including a complete autopsy and scene review, reveals no other cause of death. (Correct answer)
Correct answer: A thorough investigation, including a complete autopsy and scene review, reveals no other cause of death.
SIDS is a diagnosis of exclusion. It can only be determined after a complete and thorough case investigation—which includes a full autopsy, an examination of the death scene, and a review of the clinical history—fails to identify any other specific cause of death.
Question 4: During an investigation into the sudden, unexpected death of an infant, which of the following pieces of information obtained from the caregivers is MOST critical for the investigator to document?
- The brand of formula the infant was consuming.
- A detailed timeline of the infant's activities, feeding, and sleep in the 24 hours preceding death. (Correct answer)
- The parents' marital status and employment history.
- The make and model of the family vehicle.
Correct answer: A detailed timeline of the infant's activities, feeding, and sleep in the 24 hours preceding death.
A detailed 24-hour history is a cornerstone of a Sudden Unexplained Infant Death (SUID) investigation. This information helps the pathologist and other investigators understand the infant's state of health, identify any potential subtle symptoms of illness, and establish the circumstances surrounding the last sleep period, all of which are vital for determining the cause and manner of death.
Question 5: An investigator arrives at a home where a 3-month-old infant was found deceased in a crib. The infant has already been transported to the hospital. To assist the pathologist's examination, what evidence from the scene should the investigator make the highest priority to collect and transport with the body?
- The infant's diaper bag from the living room.
- A sample of the carpet from the infant's room.
- The soft bedding, blankets, and pillows the infant was found with. (Correct answer)
- The entire crib structure for forensic analysis.
Correct answer: The soft bedding, blankets, and pillows the infant was found with.
The immediate sleep environment is a critical source of evidence in an infant death investigation. Bedding, blankets, and other items in the crib can help the pathologist assess for potential causes of death such as overheating, suffocation, or positional asphyxia. These items should be collected and transported with the decedent for examination.
Question 6: Which of the following findings on an infant would be LEAST likely to be caused by a simple accidental fall from a low height (e.g., rolling off a sofa) and would require a higher level of suspicion for non-accidental trauma?
- A single, linear skull fracture.
- A small bruise on the forehead.
- Multiple fractures in different stages of healing. (Correct answer)
- A scrape on the knee.
Correct answer: Multiple fractures in different stages of healing.
The presence of multiple fractures in various stages of healing is highly indicative of repeated episodes of trauma over time, which is a classic sign of child abuse. A single accidental event is unlikely to produce injuries that occurred at different times. This finding requires thorough investigation for non-accidental trauma.
