Police in Cornelius, Oregon, announced on Monday that the investigation into the tragic deaths of Hong Phuong Le, 37, and her three young children has been formally closed. Detectives determined that Le killed her 7‑year‑old son Thanh Tien Dam, 5‑year‑old daughter Ha Ngan Dam, and 2‑year‑old daughter Viena Mai Dam before ending her own life on April 8, 2025.
The victims were discovered in a home on the 300 block of North 15th Avenue. Oregon State Police Forensic Services Division performed DNA testing on evidence collected at the scene to rule out any other possibilities. The results supported the detectives’ early belief that the mother was responsible for the deaths.
District attorney review confirms findings
On November 3, the Multnomah County District Attorney’s Office completed its review of the case and communicated to the sheriff’s office that its conclusions were consistent with the investigative findings. With both law‑enforcement and prosecutorial agencies in agreement, the case was officially closed.
Sheriff’s office remarks on community impact
In a release, the sheriff’s office expressed sympathy for the family, friends, and broader Cornelius community, noting the profound impact of the tragedy. “We hope the conclusion of this investigation provides some measure of closure to those affected, and we appreciate the community’s patience as investigators worked to ensure a thorough and complete review of the evidence,” the office said.
While the investigation has ended, local officials and community leaders continue to offer counseling resources and support services for residents coping with the loss. The sheriff’s office encourages anyone struggling with grief or mental‑health concerns to reach out to available hotlines and local support networks.
This case underscores the importance of timely forensic analysis and inter‑agency cooperation in resolving complex investigations. Cornelius authorities remain committed to public safety and to providing transparent communication during difficult incidents.
