Multnomah County Sheriff’s Office is investigating a deadly Fourth of July weekend boating crash on the Willamette River.
This investigation began at 11:24 pm on Saturday, July 4, 2026, when the Bureau of Emergency Communications received a 911 call reporting a boat had run ashore in the 14900 block of Northwest Gillihan Road on Sauvie Island.
When crews arrived, they found a woman dead. The Sheriff’s Office identified her as 25-year-old Rosalyn Albornoz Lopez. Paramedics took four other people to the hospital, including the boat’s operator. None of the four people have life-threatening injuries. The ages of the passengers are 21, 23, and 24. The driver is identified as a 51-year-old man.
The Sauvie Island Fire Department, American Medical Response, and the Multnomah County Sheriff’s Office responded. Based on the preliminary investigation, the boat – described as a 33-foot cabin cruiser – hit a portion of an aluminum walkway that extended to a dock, anchored by several large vertical pilings.
The cause of the crash remains under investigation. At this point, it is too early to determine if speed, impairment, or lighting conditions were contributing factors.
Authorities also said no arrests have been made.
