BUFFALO, N.Y. ( WKBW ) Evidence a Getzville doctor was speeding when he allegedly struck and killed a teenager on a skateboard last summer was presented today during his manslaughter trial.

Channel 7's Ed Reilly reports that scientific testimony was presented Tuesday morning as Amherst Police senior investigator Robert McMahon once again took the witness stand.

On Monday, investigator McMahon testified that police collected 184 measurement points using a piece of high tech equipment called a "total station."

That data was plugged into a special computer program that created scale diagrams showing what happened the night of July 8, 2011.

Robert McMahon told the court that based no the damage to the car, he believed Alexandria Rice was riding her long board in a "low squat angle."

The computer calculated that the crash sent her body flying a minimum of 40 feet through the air, before skidding 39 feet along dry concrete, and then coming to a final rest 167 feet from the point of impact.

McMahon said knowing how far the body was thrown, and the distance it skidded, was important because investigators used those numbers to calculate the speed of the car.

According the computer calculations, Dr. Corasanti was traveling between 46 and 53 MPH when he hit Alexandria Rice.

The speed limit in that section of Heim Road is 35MPH.

Eyewitness News will continue to cover the Corasanti trial, with legal analysis from defense attorney Barry Covert.
