33-year-old Ah Le Fang resides in Fullerton with his mother Lu Thao, her boyfriend and his sister. Late one evening Fang began arguing with his sister resulting in closing himself into his bedroom and refusing to open the door. When his mother attempted to communicate with him, Fang allegedly emerged from his room with a knife in his hand and stabbed 50-year-old Thao in the stomach, and her 75-year-old boyfriend in the arm. He then ran out of the home.
Thao called 911 to report that she and her boyfriend had been attacked. When Fullerton police responded they discovered she was suffering from a laceration to her abdomen, and her boyfriend with a deep gash on his arm. Both injured parties were transported for medical treatment. Thao’s wound was fatal, and it was reported that her boyfriend was in serious condition.
Despite Fang fleeing he was quickly found by police. Upon investigation the officers also discovered a knife that they speculate is the weapon that was used in the assaults. Fang was taken into custody and he is being held on $1 million bail. He faces charges of felony murder, attempted murder, and a sentencing enhancement for premeditated murder.
