A New Methodology for Visualization of Latent Fingerprint Using Mucuna Pruriens Powder in Household Appliances-Observational Study

Abstract

Introduction:

Fingerprints are considered as one of the most valuable type of physical evidence where criminals are left and serves as a decipher for the crime scene and to know the individual.

Materials And Methods:

The sample is taken in powder form. Based on the previous research work articles will be collected and the work be carried out accordingly. Mucuna pruriens  is collected and dried for 7 days. After that it was kept in the shade dry for 3 days. Then it is made into powder form. Then using the powder fingerprint dusting is done. Randomly selected people are asked to make finger impressions on the household appliances. Then using the prepared Mucuna pruriens those fingerprints are dusted. Fingerprint powder is applied by brushing it on the surface. It mechanically adheres to the oil and moisture components of the latent print. When the powder particles adhere to the grease or moisture forming the latent prints, it causes them to become visible. And pictures of those fingerprints are taken for records

Result:

The diagram is recorded and photography was taken and recorded

Conclusion:

From Mucuna pruriens, we can get visible fingerprints and also we can make fingerprints using the powder. . Further tests and studies have to be done to make it an effective potent powder that is dusting powder readily and cheaply accessible for fingerprints and thus we are making innovative and novel approach to solution of the forensic analysis
