A 15-year-old boy in Washington state stands accused of murdering his parents and three siblings in their family mansion. He allegedly attempted to frame his younger brother for the massacre by claiming the younger brother was caught watching pornography the night before. The teen’s reported plan was to make it appear as though his 13-year-old brother, who was among those killed, carried out the murders after being caught watching pornography. Investigators claim that the accused teen tried to stage the crime scene to make it look like his brother was responsible and even placed a pistol in the younger brother’s hand, although forensic evidence showed that the gun had not been fired during the crime.
The parents of the children, Mark and Sarah Humiston, were described as strict and religious, homeschooling their children and carefully controlling who they associated with. The tragic incident was reported to authorities through a 911 call placed from the family’s home in Fall City early in the morning. The surviving 11-year-old sister stated that her brother used their father’s handgun to kill their parents and siblings in the house. According to charging documents, the teen’s violent outburst was triggered by academic struggles and disciplinary issues at school.
The surviving sister recounted the terrifying moments of the night, describing how her older brother entered her room and shot her in the hand and neck before seemingly killing their younger sister. She pretended to be dead as he touched the bodies of his other victims before leaving the room and returning. After he left again, she escaped through her bedroom window and sought help from a neighbor. Police arrived at the scene following calls from the suspect and the surviving sister and apprehended the teenager as the primary suspect based on the sister’s identification.
The accused teen was charged with five counts of first-degree aggravated murder and one count of first-degree attempted murder. He is currently being held at a juvenile detention facility in Seattle and is expected to appear in court on Friday. The tragic incident has left a community reeling from the loss of a family and grappling with the shocking details of the alleged crime. The surviving sister’s bravery in escaping and seeking help has been commended, while the authorities work to piece together the events that led to such a devastating outcome. The motive behind the accused teen’s actions and the impact on the surviving family members remain critical aspects of the ongoing investigation.
