DENVER — Prosecutors say a Denver SWAT officer was justified in fatally shooting a suspect who was using a hostage as a human shield.

In a report released Friday, Denver District Attorney Mitch Morrissey says no charges will be filed against police technician Vincent Matthews for shooting 34-year-old Blas Leroux at a convenience store on Jan. 17.

Morrissey's report says Leroux pretended to be gripping a handgun in his sweatshirt pocket and pushing it against the hostage's back. He was forcing her to leave the store with him when the officer fired, hitting Leroux in the neck.

Leroux fell to the ground and was taken to a hospital, where died three days later.

Matthews told investigators he believed Leroux was going to shoot the hostage.

Officers later found Leroux wasn't armed.
