A military veteran is dead after leading multiple police agencies in a chase across state lines between Washington and Idaho.

It began around 7 pm Tuesday night in the city of Spokane and continued all the way to Coeur d'Alene before the suspect turned around - eventually stopping in the Spokane Valley.

Investigators say the suspect called them and told them that he had multiple weapons and a bullet proof vest, and that he would start shooting civilians if officers waited too long to shoot him.

When the man finally stopped his vehicle, deputies surrounded him and tried to take him into custody but the suspect pointed a gun at himself and tried to unzip the bullet proof vest he was wearing.

"From what I'm understanding, he was having some issues and was possibly suicidal and wanted law enforcement to assist with that," said Sheriff's Deputy Mark Gregory.

Sheriff Ozzie Knezovich revealed the man was a war veteran who had served a tour in Afghanistan and was awarded a Purple Heart for his service.

Washington State Patrol and Spokane Police are investigating along with the Spokane County Sheriff's Office. They expect to remain on the scene until some time Wednesday morning.
