The incorporation of Peter Chew’s First and Second Formulas for Bullet Trajectories represents a significant advancement in the field of criminology, particularly in the realm of crime scene investigation. By utilizing these specialized formulas, which are grounded in trigonometric principles, researchers and practitioners can adopt a systematic and scientific approach to analysing bullet trajectories and estimating crucial parameters such as distance between 2 towers and height between the shooter and his base tower, allowing We were able to estimate the shooter’s position. This is essential for effective crime scene investigation. By accurately estimating the shooter’s position, investigators can gain valuable insights into the dynamics of the crime, potentially leading to the identification and apprehension of suspects. Moreover, the ability to estimate both the distance and height between the shooter and their base tower provides a more comprehensive understanding of the shooting incident, enhancing the overall efficacy of crime scene investigations. By leveraging scientific principles and specialized tools, researchers and practitioners can enhance their capabilities in solving complex criminal cases and addressing broader societal challenges, ultimately contributing to the pursuit of justice and the maintenance of public safety.
