Accident, Crime Scene & Forensic Reconstruction/Investigation
Accident Investigation - Accidents occur when people, equipment or surroundings fail to behave
or react as expected.

CSIS's accident investigators determine how and why these failures occur.

Whether you have been in an accident, or you are representing a client in accident litigation.
Proving the truth about the accident can seem impossible. An investigator with the expertise
and credentials to complete a thorough and accurate investigation can be very difficult to find.
Combining years of experience with the power of science and advanced certifications, we can
provide everything from initial investigative support to expert reports and trial preparation.
Vehicle crash investigation and accident reconstruction use engineering, physics and pre-
crash conditions to accurately determine the reason why/how the collision occurred.
We combine roadway analysis, vehicle inspections, weather, lighting and traffic conditions at
the time of the accident to determine cause.
And we don’t stop there in pursuit of evidence for your case. CSIS also conducts interviews of
the reporting law enforcement officials, emergency medical personnel, witnesses and victim
accounts to discover what really happened. Our expert reports are some of the most thorough
in the industry, providing all the evidence you need for your case. Our accident investigation
services include complete crash investigation and accident reconstruction for insurance
companies, law firms, government agencies, commercial trucking companies and private
