State v. Lavoie

Following a jury trial, the defendant, Michelle L. Lavoie, was convicted of one count of manslaughter. See RSA 630:2, 1(b) (1996). The defendant appeals from various rulings by the Superior Court (Mold, J.), arguing that the court erred in: (1) allowing an expert witness to testify about her blood alcohol concentration (BAC); (2) striking her notice of affirmative defenses; (3) failing to instruct the jury on the defense of competing harms; and (4) failing to set aside the verdicts or suppress all blood test results because the State negligently failed to preserve her blood samples. We affirm.
