In Sammamish, Washington, 36-year-old Yiwen Lu was found dead in her bed on January 30, 2025, the victim of a gunshot wound to the cheek. Deputies recovered two shell casings near her body, and investigators say the second shot was fired at close range. There were no signs of forced entry or a struggle. A 9mm Ruger handgun was located in another room next to a drum set.

The investigation focused on Lu’s husband of two weeks, 35-year-old Brent Sachio Isaac Hamamoto. An attorney contacted the King County Sheriff’s Office after Hamamoto, who had fled the home with the couple’s one-year-old son, reported someone inside had life-threatening injuries. Hamamoto left the child with an aunt in Seattle’s Queen Anne neighborhood and later met detectives at Sammamish City Hall, where he was taken into custody. Records show Hamamoto purchased the handgun one day before the shooting and had filed for a protection order against Lu in September 2024 alleging abuse and threats. He has been charged with second-degree murder and is held on $3 million bail.

Are there details about the couple’s recent living situation or neighbors who might have seen or heard something on January 30 that could help this investigation?
