Police and the county coroner confirmed Tuesday that Jason James Shaw, 32, of Billings, was the man killed Monday by a Billings police officer.
Police also confirmed Shaw’s criminal history, which dates to 1997.
On Monday, Shaw's father and a friend who witnessed the shooting identified him to the Associated Press.
Billings Police Department Lt. Kevin Iffland and Yellowstone County deputy coroner Chad Fehr confirmed Shaw's identity Tuesday.
An autopsy Tuesday morning showed the cause of death was a gunshot wound to the abdomen, Fehr said.
Shaw was shot Monday by Officer Grant Morrison. Shaw was pronounced dead at St. Vincent Healthcare.
Shaw has a criminal history in Judith Basin and Yellowstone counties that includes felony theft, criminal endangerment and criminal mischief convictions, Iffland said.
In 2010, as part of a probation violation stemming from a 2005 incident, he was convicted of felony criminal endangerment out of Yellowstone County, according to the Montana Department of Corrections. Shaw was not under supervision by the DOC at the time of his death.
Morrison and another officer were searching for a person who ran from them on Custer Avenue near the intersection with Montana Avenue at 1:25 a.m. Monday.
Morrison spotted a car parked along the street that hadn't been there earlier and saw three people inside. As Morrison approached the car, Shaw got out from the back seat and did not follow instructions to keep his hands in view, Lt. RD Harper said.
Morrison used a Taser on Shaw, but it did not work, possibly due to thick clothing Shaw was wearing, police said.
Morrison said he saw Shaw reach in his pocket for a handgun, which turned out to be a replica of a Walther P99 that looks like a real gun. Morrison shot Shaw once in the abdomen, Harper said.
Morrison is on paid administrative leave pending an investigation into the incident.
Iffland said the department continues to investigate the shooting and that the Yellowstone County Attorney's Office will schedule a coroner's inquest to determine if the shooting was justified.
