Vehicle Collisions

Vehicular crash reconstructions are a core specialty of JEA. Our Forensic Engineers provide an investigation into the factors involved in the crash and determine the crash and injury causations. The investigation and analysis include documentation and analysis of evidence from the scene, vehicles, and eyewitnesses’ statements. Our Forensic Engineers evaluate the vehicle components that may have contributed to the crash.

Product Liability

Claimed injuries or property damage resulting from a product failure represent what it known as Product Liability. JEA can determine if poor design, manufacturing, maintenance, material quality, or consumer negligence is the cause of the failure.

Premises Liability

Premises liability cases can result from the property owner’s negligence in permitting a hazardous condition on his property, or as a result of negligence on the part of the injured. Often, an investigation is required so that a court may determine who is at fault, and to what degree. JEA has decades of experience in the investigation and reconstruction of premises liability accidents.

Evidence Storage

Located onsite at our property’s main headquarters in Northwest San Antonio, our secured & monitored facility offers a single point of entry and is operated by full-time staff. Facility is equipped with inspection bays, lifts, equipment. The facility also provides inspection monitoring and recording.
JEA maintains all necessary storage equipment for tamper-free evidence storage. While litigation is ongoing, we offer outdoor and indoor storage options. Our storage items include automobiles, trucks, machining equipment, construction, vehicle components, motorized recreational vehicles and assorted perishables. We maintain forklifts and all necessary storage equipment for tamper-free evidence storage.
