A suspect who died in a shootout Monday aboard an Amtrak train in Tucson has been identified as 26-year-old Darrion Taylor by the Pima County Medical Examiner's Office.

Taylor died from "gunshot wounds of the trunk and extremities," according to Dr. Gregory Hess, who oversees the office. "The gunshot wounds were not self-inflicted."

A complete autopsy report will not be available until November.

DEA agent Michael G. Garbo of Sahuarita, a 16-year veteran of the agency, died in the exchange. Another man, identified as 22-year-old Devonte Okeith Mathis, was arrested.

Court documents indicate that the officers boarded the train with a list of suspects, including Mathis and Taylor, and that Mathis was carrying about 5 pounds of marijuana and 50 packages of marijuana edibles.

Garbo’s funeral is set for 10 a.m. Friday at a Calvary Chapel in Tucson. It will be live-streamed at: https://live.calvarytucson.com.
