Autosomal STR (Short Tandem Repeat) analysis is commonly used in forensic science field for personal identification. However, it is impossible to determine identity of monozygotic twins using STR analysis but, there is a case which can be solved because of the nature of identical twin. We found out a male DNA from blanket which suspect through away during his escape matched one of the inmates who has twin brother. Then, police have pointed out inmate’s brother as a suspect and arrest him. We can spot a suspect easily because his twin brother is held in prison although most of the time we have difficulty determining who commit the crime. In these days, there are many scientists run various studies about identification of monozygotic twins. However, we have to solve some of the practical problems like time and cost to apply on the forensic area.
