As many as 80 witnesses could be called by the prosecution as it builds its case against Dr. James Corasanti, the Amherst doctor charged in connection with the death of an 18-year-old teenager.
The trial begins today as opening statements will be heard in Erie County Court.
Judge Sheila DiTulio estimates it will take a month for jurors to hear testimony before deciding on the many charges facing Corasanti.
Prosecutors say Corasanti was drunk when his vehicle struck and killed Alexandria Rice on Heim Road last July.
Charges include manslaughter, leaving the scene of an accident and tampering with evidence.
