Asphyxia typically occurs due to oxygen deficiency in confined spaces. A male researcher died in a minor car accident. He had loaded a container filled with liquid nitrogen in his car the day before the accident. Clinical analysis of blood showed that blood alcohol concentration(BAC), carboxyhemoglobin (CO-Hb), drugs and toxins were negative. During the car investigation, it was found that there was frost around the lid of the liquid nitrogen container with a trace amount of liquid nitrogen left. To determine the cause of death, the simulation test was performed by reconstructing the situation of liquid nitrogen leaking in a confined space. The results showed that liquid nitrogen in the container was continuously evaporated and reduced the oxygen concentration in the car. After 20 min the state of oxygen deficiency was reached and then the oxygen concentration was cut down to 6.5 % within 10 hours. It was concluded that the cause of death was oxygen-deficient circumstance resulted from the evaporation of liquid nitrogen in the car. In order to determine the cause of death, it is necessary to perform a simulation test considering all potential factors that may affect the accident.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
