BUFFALO, NY (WKBW-TV) After two days on the witness stand, Dr. James Corasanti is now finished giving testimony in his hit-and-run manslaughter case.

Under an aggressive cross-examination, the doctor maintained that he never saw 18-year old Alexandria Rice on the night of July 8, 2011.

Corasanti testified that he heard and felt a thud, but never saw the girl.

Assistant District Attorney James Bargnesi ask the doctor if he noticed the 8-inch high damage on the car's hood, the glass that was knocked out of his passenger side mirror, and the misaligned right headlight after the impact.

The doctor replied, "No."

Dr. Corasanti also faced several questions about his failure to call 911 or Amherst Police, after he knew that the accident involved a person. The doctor insisted that he contacted his defense attorney, Tom Burton, and assumed the lawyer was making the notifications.

Judge Sheila DiTullio advised the jury that using a lawyer should not be viewed in a negative context.

During the afternoon session, the defense called toxicologist Dr. Jimmie Valentine from Arkansas.

The retired doctor testified that blood alcohol tests taken from Dr. Corasanti's five hours after the fatal accident were "meaningless."

Dr. Valentine told the court that the instrument doing the test was not properly calibrated, and he said there were indications that Dr. Corasanti's blood sample showed signs of being contaminated.
