TEMECULA — Riverside County Sheriff’s Department posted a statement regarding an incident involving a knife-wielding man that happened at Costco in Temecula on Thursday, Jan. 7. 

“We responded to a call of a male possibly armed with a knife at the Costco located on the 26000 block of Ynez Road in Temecula,” according to the Sheriff’s Department’s post. “The male was detained with the assistance of civilians. Upon arrival, deputies took the male into custody.

“There is NO ACTIVE SHOOTER and no threat to the public.”

The active shooter comment was in response to some social media posts wrongly reporting that there was an active shooter at the big box retailer. 

In a Facebook post shared with Valley News and written by the wife of a federal agent, Temecula resident Brian Miller, who she said intervened in the incident to subdue the knife-wielding man. 

“My husband was a hero today and I couldn’t be prouder,” Kryssa Miller wrote. “While we were checking out we noticed a disturbance and a man approaching us with a large serrated knife in his hand.

“Brian drew his weapon, gave commands to drop the knife, and with the help of another off-duty LEO, safely got the suspect disarmed and on the ground. 

“He saved lives today and I am so grateful he decided to go shopping with me. I am so tired of the anti-police rhetoric, today a very special one put himself in harm’s way to protect others.”

Valley News reached out to the Riverside County Sheriff’s Department to confirm statements and request more information, but they have yet to respond to requests. 

The department wrote in their Facebook post that the incident is an ongoing investigation.
