Abstract: Various kinds of events such as mass disasters or mutilated murders can cause a persons limbs to be unrecognized and even pieces of his body separated. If this is the case, the estimation of height is a major step in the process of identifying the unknown person. Research on the fingers is important to do to determine a persons identity because a body piece that is found is not always in the form of a long bone, it can also be found in the form of a short cut like a finger. Objective: This study aims to determine the relationship between the length of the middle finger and the height of the residents of Perumahan Citra Wahana I in Deli Serdang Regency.
