Police in Council Bluffs said Wednesday that a former Lewis Central student whose body was found late last year in the back seat of a vehicle in the parking lot of a J.C. Penny store off of Marketplace Drive, died of alcohol poisoning. Authorities say an autopsy determined 15-year old Mireya Mata-Alvarez‘ death the night of Dec. 21st was ruled “accidental.” The cause was listed as “acute ethanol intoxication,” which is commonly referred to as “alcohol poisoning.”  The girls’ blood alcohol level registered more than five-times the legal limit of .08. No foul play was involved.

Officials say Mata-Alvarez had been with two juvenile girls and five juvenile males earlier that same evening. Both girls – one of whom dialed 911 – were on scene when emergency crews arrived, but the boys were no longer present.

Mata-Alvarez had attended Lewis Central High School during her freshman year, but was not enrolled for her sophomore year, because she had transferred out of state.
