Update 12/9, 8:30 am:

Portland police have updated their original narrative about the Monday incident. According to a Portland Police Bureau (PPB) press release, detectives have now determined that the victim of the carjacking "who reported that she had been shot was not in fact injured by gunfire."

"They're working to determine the cause of her injury," PPB writes.

The bureau has also identified the deceased carjacker as 30-year-old Brandon Keck.

Update 12/7, 10:20 am:

Portland officer John Hughes has been identified as the officer responsible for fatally shooting an alleged carjacker yesterday. Hughes, who has worked for the bureau for 17 years, has been placed on administrative leave for the duration of the investigation. Hughes has made headlines for his conduct at the bureau in the past. In 2008, Hughes was sued by an individual who accused Hughes of tasing him while he was on his knees with his hands behind his head. The city settled that lawsuit in 2010.

Update 12/6, 3:30 pm:

Portland police shot and killed a man accused of carjacking Monday morning.

According to Portland Police Bureau (PPB) spokesperson Nathan Sheppard, PPB officers responded to a home invasion robbery call Monday morning. During that robbery, police say an armed person stole a vehicle and then proceeded to commit "several more" carjackings before driving onto Interstate 5 against traffic.

According to Sheppard, the armed individual then attempted another carjacking on the freeway, during which an occupant of the vehicle was shot. That victim was transported to the hospital with non life-threatening injuries.

PPB officers then shot and killed the armed suspect. This is the fourth fatal shooting by PPB officers this year.

In a tweet following the shooting, PPB Chief Chuck Lovell said while "it is disturbing that one person was injured, I am grateful it was not worse and that no others—including our officers—were injured."

Both lanes of I-5 remain closed to traffic. The Oregon Department of Transportation (ODOT) is directing northbound drivers off the interstate at North Greeley Avenue and southbound traffic must exit at North Victory Boulevard.

Original story:

Portland police shot a person accused of committing a series of armed carjackings Monday morning on Interstate-5, shutting down a significant section of the freeway in North Portland.

According to a press release, officers with the Portland Police Bureau (PPB) responded to reports of multiple armed carjackings shortly before 10 am Monday morning in the area where I-5 intersects with Rosa Parks Way. This armed individual allegedly shot a member of the public while attempting to steal a car, sending the victim to the hospital with a non-fatal wound.

In the press release, PPB vaguely notes that, "At some point, deadly force was deployed by police." It is not immediately clear if the alleged carjacker was injured or killed by this force, as police use the term "deadly force" whenever they fire a gun—regardless of the outcome.

PPB did not respond to the Mercury's request for clarification, yet the Oregonian is reporting that the individual has died.
