A man arrested last year for stabbing his younger siblings to death now says he did so because he wanted to be by himself.
19-year-old Malik Vincent Murphy, a community college student from Colorado Springs, Colorado, is alleged to have stabbed his 5-year-old sister Sophia Murphy and 7-year-old brother Noah Murphy to death while they slept on October 17. After his father Jefferson Murphy, having heard his daughter's screams, left his bedroom to try and check on her, Malik stabbed him in the neck; though he later recovered, both children died from their injuries.
People reports that during a three-hour long court hearing on Friday, prosecutors played Murphy's videotaped interrogation, during which he allegedly told investigators that he'd thought about killing his family for months.
"I can't stop thinking about killing people," he reportedly said at one point. He is also alleged to have said that killing his siblings was "something that (he) had to do," and when asked why he wanted to kill everyone in his house, he responded, "to be by myself."
Also discussed during the hearing was Murphy's history of violent thoughts and mental illness; Murphy had been committed to psychiatric facilities multiple times and, two years before the 2017 killing of his siblings, hid in the bathroom of his high school, planning to strangle the next person who entered. He ultimately abandoned his plan because he was worried about being overpowered during a potential attack.
Murphy also told police that he'd been diagnosed with depression and anti-social personality disorder, The Gazette reports, and admitted that he had not been taking his depression medication. Murphy's public defenders are reportedly planning to use a mental health defense, and asked about footage that was reportedly edited out of the interrogation video that shows Murphy talking to himself, saying, "No, no, no," "Oh my God, why?" and "Malik, what did you do?"
Murphy is facing two counts of first-degree murder and an attempted first degree murder charge. He is due back in court for arraignment on April 9.
