Teenager Charged in Connection with the Fall City Murders
Early on Monday morning, at approximately 4:55 a.m., authorities received multiple 911 calls reporting gunfire in the Lake Alice neighborhood of Fall City, a small community located 25 miles east of Seattle. King County deputies arrived at the home of Mark and Sarah Humiston to find the bodies of two adults and three juveniles, all fatally shot. The young suspect, reportedly the 15-year-old son of the family, was taken into custody shortly after, while another family member, an 11-year-old girl, was found injured and rushed to Harborview Medical Center for treatment.

The victims were identified as 43-year-old Mark Humiston, his wife Sarah Humiston, 42, and three of their children: Katheryn (7), Joshua (9), and Benjamin (13). Four of the five victims suffered gunshot wounds to the head, according to the King County Medical Examiner’s Office. Authorities have yet to release further details about what may have led to this tragic event. However, court documents reveal that the suspect may have attempted to stage the crime scene to make it appear as if his brother had committed the murders and then taken his own life.

Troubling Details Amidst Investigation
Authorities quickly initiated a thorough investigation into the Fall City murders, uncovering unsettling details about the case. Police reports indicate that the teen suspect initially called 911, claiming his brother had shot the family members before taking his own life. The scene was staged to support this story, with one of the firearms placed near the body of the 13-year-old brother. However, statements from the surviving sister contradicted this narrative, leading authorities to suspect foul play by the 15-year-old.
In court on Tuesday, Judge Joe Campagna ordered secure detention for the suspect, citing “the highest possible risk to community safety.” Defense Attorney Amy Parker emphasized that these allegations are yet to be proven, adding that the suspect, who has no prior criminal history, enjoyed activities like fishing and mountain biking. The community remains stunned as they try to process the devastating tragedy that has left them mourning the loss of five beloved residents.
Community In Shock and Mourning
Fall City, a quiet, rural town, has been deeply impacted by this tragedy. Known for its close-knit community and scenic landscapes, residents are struggling to come to terms with such a horrific crime within their midst. Many community members knew the Humiston family and described them as dedicated parents and active members of the local community. The family had homeschooled their children and were well-regarded by neighbors and friends alike.
One resident, Lynne Trowern, expressed her shock, saying, “I’m just in total shock. I keep bursting into tears.” Mark Humiston was an engineer and a respected colleague, remembered by his coworkers as a leader and friend. His employer released a statement, expressing deep sadness over the loss and extending condolences to his surviving family members.
Support and Vigil for the Victims
In the wake of the tragedy, community members have gathered to honor the victims and offer support to one another. Fall City United Methodist Church hosted a vigil on Tuesday evening, where Pastor Carrie Bland shared her sorrow with those in attendance, stating, “The loss of this family, taken so cruelly and senselessly, has left us heartbroken, devastated, and struggling to understand how such pain could exist in this world.” Counseling services have been made available to help residents process the events and cope with the emotional fallout.
Next Steps in Legal Proceedings
The suspect is scheduled for another court appearance on Friday, October 25. While the community awaits more details about the motive and circumstances behind the Fall City murders, authorities have reassured residents that there is no ongoing threat to the community. Sheriff Patricia Cole-Tindall called the incident “very sad, very disturbing” and emphasized the need for additional resources to aid both first responders and community members affected by this tragic event.
