Buffalo,NY (WKBW)- After a one day break, testimony resumed Thursday in the manslaughter trial of an Amherst doctor accused in a hit and run crash.

Doctor James Corasanti faces vehicular manslaughter charges in the death of 18-year old Alexandria Rice. Prosecutors say Corasanti was drunk, texting, and speeding before he struck the teen with his car on Heim Road in Amherst last July and then fled the scene.

Thursday in court, Millard Fillmore Suburban Hospital Registered Nurse Hope Dalrymple testified she observed that Corasanti had glassy eyes while she performed a blood draw.

Dalrymple says it took a second attempt to obtain the doctor's blood after the 1st attempt failed. The defense is questioning the integrity of the DWI blood kit, which is used to test suspects, and believes that could explain why the nurse had difficulty drawing blood. They also argue the preservatives inside the test tubes could have contaminated the results.

Experts say Corasanti's B.A.C. was .10 several hours after the crash.

Several days after the crash, the blood sample was tested by a toxicologist and a forensic toxicologist at the Erie County Medical Examiner's Office. Certified Toxicologist Colleen Corcoran told prosecutors the samples were left in a locked refrigerator over that weekend, before the testing, and then transferred into a secure area.
