An arrest at a Raleigh Hills care facility has put a spotlight on a problem that families across Oregon worry about but rarely discuss until it affects their own household. When someone we love enters a care facility, we expect protection, not further harm. This case is a reminder that oversight can fail, and when it does, families have legal options.
What Happened in Raleigh Hills
According to the Washington County Sheriff’s Office, deputies investigated a reported sexual assault at a care facility in the Raleigh Hills area and arrested a caregiver accused of sexually abusing an elderly resident. On May 9, 2026, staff at the facility contacted police because they were concerned that a resident had been sexually abused by an employee, and a detective from the Violent Crimes Unit was assigned to lead the investigation.
Investigators identified the accused as 25-year-old Oscar Marquez-Alonso, who had worked as a caregiver at the facility for approximately one month. Detectives found evidence that he sexually abused an elderly female resident while on duty, and he was arrested and lodged at the Washington County Jail on two counts of sexual abuse in the first degree and one count of sodomy in the first degree.
The investigation hasn’t closed. Detectives said the case remains open and that Marquez-Alonso may face additional charges, noting concern that there could be additional victims. In many nursing home abuse cases, one reported incident is the visible edge of a broader pattern that a facility failed to catch, or chose not to report.
Why These Cases Are Hard to Spot
Sexual abuse in a care setting rarely announces itself. Residents may have cognitive impairment that makes reporting difficult or unreliable. Staff turnover can bury red flags. And facilities sometimes have incentives to handle allegations quietly rather than escalate them.
Families and staff members who suspect abuse should watch for a cluster of warning signs rather than any single symptom:
- Unexplained bruising, particularly around the inner thighs or torso
- Sudden anxiety or fear around a specific staff member
- Torn, stained, or missing undergarments
- Changes in sleep, appetite, or willingness to be touched
- Reluctance to be left alone with a caregiver
No single sign proves abuse occurred. But a pattern, especially one that develops shortly after a new employee starts, deserves a direct conversation with facility management and, if warranted, a report to Adult Protective Services or law enforcement.
Facility Responsibility Beyond the Individual Caregiver
An arrest addresses the criminal side of a case like this. It does not automatically address whether the facility itself failed to protect its residents. Care homes have a duty to screen employees properly, supervise staff adequately, and respond quickly when concerns are raised. A civil claim can examine whether the facility ran background checks, whether prior complaints existed, and whether staffing levels made abuse more likely to go unnoticed.

What Families Can Do Right Now
If you suspect a loved one has been harmed in a care facility, documentation matters more than confrontation in the early hours. Photograph any visible injuries. Write down dates, times, and the names of staff present. Request a copy of the resident’s care plan and recent incident reports. Facilities are required to maintain these records, and a paper trail built early tends to hold up better than memories reconstructed months later.
It’s also worth contacting the Oregon Department of Human Services, which licenses and inspects long-term care facilities statewide. A state inspection can run parallel to any criminal case and often produces findings that support a civil claim.
