Missoula Police are working with detectives from Spokane, Washington after a man was found shot to death in a vehicle outside St. Patrick Hospital on Sunday afternoon.

Detective Sergeant Scott Pastian said the victim was driven to Missoula from Spokane, and either died en route to Missoula, or was deceased inside the vehicle for the entire trip.

"We're looking into the possibility that the death occurred in Spokane," Pastian said. "Spokane detectives are here in Missoula right now and we're conducting a collaborative investigation to try and determine how he died."

Pastian said authorities are investigating the shooting death as a homicide.

The shooting victim has been identified, but  officials are not releasing the name at this time.

Brenda Bassett with the Missoula County Sheriff's Office told KGVO News that the identity of the victim would have to be released from the Spokane County Coroner, since the death apparently occurred in that jurisdiction
