Medical toxicology expert witness Dr. Gary Dawson testified in the Provo, UT, murder trial of Martin MacNeill. MacNeill is accused of giving his wife five drugs including Valium which caused her death in 2007. Pharmacist Dawson described drugs found in Michele MacNeill’s body and how they are processed in the body. The prosecution contends that MacNeill killed his wife in order to continue an affair with Gypsy Willis while the defense says Mrs. MacNeill died due to a hear condition.
