A Washington County care facility in the Raleigh Hills area is at the center of a disturbing criminal case after detectives say a caregiver sexually abused an elderly resident while on the job. Authorities have identified the suspect as 25-year-old Oscar Marquez‑Alonso and say the alleged abuse happened during one of his shifts. The investigation kicked off on May 9, when staff members raised alarms about the resident’s welfare.
According to KPTV, Marquez‑Alonso is now facing two counts of first-degree sexual abuse and one count of first-degree sodomy. Detectives say he had been employed at the facility for roughly a month before staff reported concerns, and investigators say they uncovered evidence tying him to the alleged abuse. The Washington County Sheriff’s Office added that Marquez‑Alonso could face additional charges as detectives continue gathering information.
Investigation and Reporting
The case lands in a state system that already logs thousands of reports involving older adults each year. According to the Oregon Department of Human Services, Adult Protective Services recorded 18,535 alleged victims in 2024, a stark reminder of how often harm to older Oregonians is reported. ODHS highlights Oregon’s SafeLine at 1-855-503-SAFE (7233) as a confidential resource for reporting abuse and getting help. The agency urges community members and facility workers alike to watch for signs of physical or sexual abuse and to report any red flags quickly.
Prosecutions in Oregon
Prosecutors in Oregon have pursued similar cases in recent years. According to the Oregon Department of Justice, a caregiver in Eugene was sentenced in January to 15 years in prison after sexually abusing an 86-year-old memory-care resident. The DOJ said that prosecution relied on coordination with local agencies and the state crime lab and called the case a reminder of how vulnerable residents with cognitive impairments can be. Advocates say that coordinated, trauma-informed investigations are crucial for holding abusers accountable and supporting victims through the process.
What’s Next
The Washington County Sheriff’s Office says detectives are still actively working the Raleigh Hills investigation and that Marquez‑Alonso could face more charges as the case unfolds. Anyone who believes they may have been victimized or who has information is urged to call the sheriff’s office Investigations Division at 503-846-2500 and reference case number 50-26-6407, according to KPTV. Prosecutors are expected to review the findings and determine formal charges as new evidence comes in.
