Identification of latent fingerprint in crime scene is one of the most important thing for crime scene investigators. Lots of fingerprint identification methods have been developed to be applied to various kinds of evidence. Nowadays, forensic DNA typing technology showed incredible sensitivity of successful result even from fingerprint. In this study, six kinds of fingerprint identification methods including Ninhydrin, Ninhydrin with heat, DFO, iodine, RTX and CA were examined regarding to their effect to DNA profiling by quantitative analysis of purified DNA using quantitative PCR. The fingerprint chemicals were treated onto the diluted bloodstain on paper following purification of DNA after 1, 3, 5 and 7 days. RTX treatment resulted approximately 70 % decrease in DNA concentration showing the most destructive or inhibitory chemicals. Ninhydrin with heat treatment and ninhydrin only treatment showed approximately 50 % and 30 % decrease, respectively. DFO, Iodine and CA showed relatively little effect on DNA concentration of 10 % to 20 % decrease. The effect of fingerprint chemicals on forensic DNA typing was also demonstrated by STR analysis. Latent fingerprint identification and DNA typing are equally important forensic tools. It is necessary to establish a guideline for selection and sequence of latent fingerprint identification method for successful DNA typing from fingerprint.
