Background: Latent Fingerprints or chance prints are found at crime scene on various substrates and one among them is wet conditions. There is an urgent need for the development methods as well as studies related to their persistency on wet conditions.
 

Methods: The development of fingerprints by powder method was adopted for fingerprints found in various substrates.
 

Results: It is clear from the figures that on all the surfaces fingerprints could be developed after one day whereas on glass the fingerprints could not be developed after one day.

 

Conclusions: There are numerous techniques available for the development of fingerprints from various substrates under different conditions but hardly there are methods for development of fingerprints found in wet conditions. The present study deals with a powder method (rangoli colors) for the development of fingerprints found under wet conditions. The advantage of rangoli powders are that they are less expensive, non-toxic, and simple methodology of the development of latent fingerprints that can be employed on different substrates. Out of the five surfaces taken for study it has given successful results in all of them in which latent prints development was possible though found in wet conditions.

Background: Age identification can be estimated based on epiphyseal fusionlocated in the region of interest of the distal femoral bone. There is an age difference in fusion epifisis indonesian compared to other countries. this is due to differences in population, nutrition, and individual respectively. This cross-sectional study aims to investigate the relationship between the stage of epiphyseal union on the bone of the femur and biological age.

 

Objective: This research is expected to be applied as media of age identification on body frame without doing cleansing of body tissue, nor in human being alive and simplify and shorten age identification process.

 

Methods: Distal femur x-ray images will be examined in men and women by age 15 to 20 years. Epiphyseal fusion is divided into five specific stages of the femur, tibia and fibula. Fusion is rated as stage 0: beginning union1: initial union, stage 2: active union, stage 3: recent union, and stage 4: complete union

 

Results: Based on the age distribution of 15 to 20 years, the second phase will begin at the age of 15 to the age of 17 years and will follow the second stage based on the development and age. Epiphyseal fusion in the second stage is more common at the age of 15 years. First stage epiphyseal fusion in men begins at <15 years and <15 years in women.

 

Conclusions: The results of this study indicate that biological age forensic identification can be estimated based on epiphyseal fusion
