New technologically advanced 3D computer reconstructions allow the viewer to see real images of the crime scene much like watching a television show. The virtual world can be created using 3D lasers and computer software. The crime scene is taking on a completely different view. No longer is the crime scene restricted to inside of the crime tape. It has moved beyond a physical barrier allowing analysts to dissect the crime scene to identify evidence often missed simply walking through the traditional steps of sketching. There is now the opportunity for anyone to revisit the crime scene the next day, next week, or years from now. This is an important function to allow the jury to see exactly what the investigators and witnesses saw at the crime scene leaving nothing to the juror’s imagination.
According to the Department of Safety for the State of Connecticut, forensic crime scene reconstruction “is the process of determining the sequence of events about what occurred during and after a crime” (Department of Public Safety - Scientific Services, 2010). Crime scene reconstruction normally starts ideas of what happened
