PRESCOTT, AZ - A coroner's office says 19 elite firefighters killed over the weekend died from burns and inhalation problems.
The Maricopa County Medical Examiner's Office in Phoenix issued the finding Thursday, two days after performing the autopsies.
The firefighters had deployed Sunday to what was thought to be a manageable lightning-caused forest fire near the small town of Yarnell.
Violent winds turned the fire, taking the crew by surprise and killing the Hotshot team.
Officials said the memorial services for the fallen hotshots have been scheduled for Tuesday, July 9 from 11 a.m. to 1 p.m. at Tim's Toyota Center in Prescott Valley.
APS told ABC15 it will be covering the costs associated with this service.
The 19-hearse procession from Phoenix to Prescott will take place Sunday morning.
Authorities said $800,000 has so far been raised for the families of the victims.
Nearly 700 fire personnel are fighting the Yarnell Hill Fire near Prescott, and have been able to boost containment from 8 percent to 45 percent as of 6 p.m. Wednesday.
According to Incident Command, crews expect to have the fire fully contained by 12 a.m. Friday, July 12.
