BUFFALO, NY (WKBW-TV) A collision reconstruction report, prepared by Amherst Police Senior Investigator Robert McMahon, shows that a car driven by Dr. James Corasanti was traveling 11 to 18 miles over the speed limit when the Getzville doctor struck and killed Alexandria Rice last summer on Heim Road.

The computer calculated report also showed that Dr. Corasanti's 2010 BMW was driving over the fog line and partially inside the bicycle lane at the time of the fatal accident.

Police collected 184 measuring points from the accident scene, and used a special computer program to generate scale diagrams depicting what happened.

Investigator McMahon previously testified that the high-tech software estimated that Alexandria Rice's body was thrown at least 40-feet in the air, before coming to final rest 167-feet from the point of impact.

Under a very detailed cross-examination, Defense Attorney Tom Burton argued that the complex formulas did not take into account the speed, or direction of travel, of the victim on her longboard.

To emphasize his point, the jury was shown the victim's broken longboard, as well as an exact reproduction, and Burton described how the wheels were capable of making sudden "cuts and moves."

Responding to questions from the defense, Officer McMahon agreed that Alexandria Rice was probably harder to see because she was riding the longboard, in what he called, "a low squat position."

The defense claims Dr. Corasanti did not see the victim as he drove along Heim Road about 11:20pm.

The trial is scheduled to resume on Thursday.
