On March 22, a son allegedly stabbing his mother with a knife at an intersection in Phoenix, Arizona, was shot and killed by an armed citizen.

According to ABC 15, a mother and her 28-year-old son got in an argument “in a vehicle near 51st Avenue and Cactus Road.” The son then allegedly began stabbing his mother until she “fell out of the vehicle.”

Even then, the son reportedly continued stabbing while bystanders ran to her aid and tried to stop him.

One of the witnesses eventually pulled out a gun and commanded the son to stop. When the man ignored the commands, the armed citizen shot and killed him.

According to AZ Family, Phoenix police say the mother was transported to a hospital in critical condition. The citizen who shot and killed the son “was not detained by police.”
