Peter Le, 52, allegedly killed his own father, Quyen Le, 86, before he was shot and killed by police. A 911 caller told dispatch around 10:30 p.m. that one of his brothers was harassing their father at their home. When police arrived, the front door was open, and an officer saw Peter Le standing with a knife and gun in his hands inside the home, police said. The officer ordered the younger Le to drop the weapon, but he continued to threaten to harm his father for several minutes, and refused to drop either weapon. Peter Le then fatally shot his father, and the officer shot and killed Le.
