Two forensics experts from the county crime lab testified that Farley had a blood alcohol level of .20 — about 2 1/2 times the legal limit — and a detectable level of two anti-anxiety medications in his system.
The testimony indicated that the prescription drugs can magnify the effects of alcohol.
Defense attorneys, however, contended that the blood was tested days after the crash and may have cultivated bacteria, which could produce additional alcohol and alter an accurate reading.
Farley sat stiff and attentive as prosecutors presented their evidence against him. About 10 friends and family members — including Sweet's mother, Elizabeth Sweet, and stepfather David Pidcock — were in attendance, as well as a Mothers Against Drunk Driving representative.
