Forensic Analysis of the Correlation of ABO Blood Group Frequency and Criminalities among Female Inmates in a Typical Nigerian Prison

Abstract

The frequency of ABO blood group was carried out among inmates in a typical Nigerian prison. This study sought to correlate blood grouping with crime to determine whether a relationship could be established. The results obtained will serve as a platform for instituting awareness to relevant authorities and the public at large. The experiment was carried out at the hospital premises of the Kirikiri medium prison Apapa Lagos Nigeria. A total of 212 female inmates voluntarily availed themselves for this study. Blood was taken by piercing the thumb with a lancet and dropped on the card. The ABO and rhesus blood grouping was determined using felines card method with commercially prepared antisera. The frequency of each blood type was calculated. Among the female inmates charged for the various crimes used in this study, blood group O  was more prominent for inmates charged for stealing (40%) , fraud (52%), robbery (41%) and human trafficking (36%) followed by blood type B  having highest frequencies for murder (51%) and drug abuse (45%) . Blood type A  has the least occurrence having highest frequency for only drug abuse (48%). This study indicates that Blood group O  had the highest frequency among inmates convicted for the various crimes except for murder and drug abuse. Blood type AB  and AB  had the least frequency when compared to other blood groups in the various crime considered. Some variations in frequencies were observed. This study therefore shows that blood type O  might predispose individuals to crimes
