A 15-year-old was arrested after he allegedly stabbed his mother to death after being inspired by a Menendez Brothers documentary. According to a criminal complaint, officers arrived at the teen’s residence at around 10:30 p.m. on March 4 after someone called 911 to report that they had been sent pictures on Snapchat that showed a woman unresponsive on the floor and pools of blood. The sender also reportedly told the caller that he had stabbed his mother to death and needed help.
