Guam - The death of a Guam Police Department officer in Yigo last week was proven to be accidental, according to Chief Medical examiner Dr. Aurelio Espinola. GPD was called to a home on Chalan Nika last week Wednesday to a reported injured person. Authorities found police officer Gerard Perez pinned underneath his jeep. The death prompted an investigation by GPD's criminal investigation division. Dr. Espinola ruled out foul play as a possible cause, and states Perez died from asphyxiation due to chest compression.
