Mr. Mancilla holds a Bachelor of Science in Physics from California State Polytechnic University, Pomona, where he studied key principles of physics, including optics, kinematics, thermodynamics, electromagnetism, and computer-aided analysis. He leverages this strong foundation in physics to conduct detailed accident reconstruction for various types of incidents, including, but not limited to, transportation accidents and premises liability cases. He also applies his knowledge of human factors and biomechanics to assist in accident reconstruction.

In transportation accident reconstruction, Mr. Mancilla uses advanced problem-solving skills to analyze critical factors such as impact angles, crush depths, velocity changes, vehicle speeds, and the forces involved in vehicular collisions. Mr. Mancilla is also certified to perform Event Data Recorder (EDR) imaging from vehicles that support it. EDR imaging can yield critical information related to vehicle collisions (like pre-impact speed, steering angle, and brake usage), and Mr. Mancilla is qualified to analyze this data. Additionally, Mr. Mancilla can also use his computer skills to create animations of different types of accidents for demonstrative purposes which can incorporate 3D Scans. Mr. Mancilla is also able to use specialized software to create simulations which can aid in accident reconstruction and creating demonstrative aids.

Mr. Mancilla employs the discipline of accident reconstruction to analyze safety in designs, practices, and procedures. His forensic investigations have included the following types of accidents: automobile vs. automobile; automobile vs. pedestrian; slip and fall; trip and fall; and premises liability.

EXEMPLAR CASE WORK

In one automobile vs. pedestrian case, the driver of the vehicle was alleged to have been speeding when they impacted a pedestrian, and it was alleged that driver inattention was a factor. Mr. Mancilla used available evidence to determine the speed of the impact of the vehicle and showed that vehicle was traveling at or under the speed limit at the time of the collision. Additionally, Mr. Mancilla used principles of human factors to show that an average driver traveling at the speed limit would have insufficient time to perceive and react to the pedestrian who stepped out into traffic.
