Blood and urine sample were collected from the two suspects.  The Toxicology Unit analyzed the blood for alcohol using Headspace-Gas Chromatography (GC) with Flame Ionization Detection (FID), which resulted in a 0.12% blood alcohol concentration on suspect #1 and a 0.18% blood alcohol concentration on suspect #2.

 

The Urine was screened for drugs using Enzyme-Linked Immunosorbent Assay (ELISA.)  Methamphetamine and amphetamine (methamphetamine metabolite) were confirmed by Gas Chromatography/Mass Spectrometry (GC/MS) in suspect #1.  Suspect #2 had negative results.
