On Thursday, a judge shot down a Colorado woman's petition to seize guns from the Colorado State University Police Officer who shot and killed her son during a 2017 edged weapon attack.

In her petition for an Extreme Risk Protection Order (commonly known as a "red flag"), Susan Holmes claimed there was a credible risk of unlawful or reckless use of a firearm by Phillip Morris because he threatened and killed her son Jeremy Holmes and had a history of being aggressive. The law only allows family or household members or police to seek the removal of guns from someone deemed a danger. Holmes says she is considering an appeal of Thursday's ruling, KKTV reports.

Jeremy Holmes was armed with a knife and had made threats against family members when an officer confronted him on July 2, 2017. The officer called out to Holmes a number of times, telling him to "drop the knife!" The officer was backing away from Holmes as he asked him to drop the bayonet knife. Holmes can be seen on video charging at the officer with the weapon before the officer opened fire in self-defense. The Larimer County District Attorney's Office ruled the shooting justified.
