TOXICOLOGY CHECKS OF BLOOD & URINE SAMPLES WERE MADE. THE CHECKS SHOWED THE PLT & PAX HAD BLOOD/ALCOHOL LEVELS OF 0.17% & 0.11% (GRAMS%), RESPECTIVELY. A DRUG SCREEN OF FLUID FROM THE PLT SHOWED COCAINE/BENZOYLECGONINE LEVELS OF 0.19 MG/L. TOXICOLOGY CHECKS CONCERNING THE PAX WERE NEGATIVE FOR DRUGS.
