Police in Council Bluffs are conducting an investigation into the death of a 15-year-old girl whose body was found Saturday in the back seat of a car in the parking lot at JC Penney in Council Bluffs. Sgt Chad Meyers with the Council Bluffs P-D, says officers were called at around 10:15-a.m., to 3333 Market Place Drive, where they found Mireya Mata-Alvarez, a former sophomore at Lewis Central High School.

A police investigation revealed Mata-Alvarez was out with two juvenile girls and five juvenile males.  Police believe alcohol or marijuana was used by the group. One of the girls called 911. Both were on scene when emergency crews arrived. Officials said the death did not appear suspicious and were awaiting autopsy and toxicology test results.
