A quiet Washington County apartment complex turned into a crime scene on March 22, 2025, after deputies say a 36-year-old man was stabbed multiple times inside his home in an unincorporated area of the county. A short time later, investigators arrested 26-year-old Rosalia Martinez-Hernandez and booked her into the Washington County Jail on attempted murder, first-degree assault and first-degree burglary charges.
What deputies say
Deputies were called to a disturbance involving a weapon on the 18400 block of NW Chemeketa Lane at about 7:40 a.m., according to KATU. The victim told deputies that Martinez-Hernandez, a woman known to him, forced her way into his apartment and stabbed him multiple times.
He was taken to a nearby hospital, where he was described as in serious but stable condition, KATU reported.
Arrest near Springville Road
As deputies searched the area, a patrolling officer spotted Martinez-Hernandez near the intersection of SW Springville Road and NW 178th Avenue at about 8:25 a.m., roughly 45 minutes after the initial call, according to KPTV. She was arrested without incident.
Martinez-Hernandez was then booked into the Washington County Jail on Attempted Murder in the Second Degree, Assault in the First Degree and Burglary in the First Degree, KPTV reported.
Investigation underway
Detectives from the sheriff's Violent Crimes Unit have taken over the investigation, and officials say additional charges could be added as the case develops, according to Right Now Oregon.
So far, authorities have not released any information about a possible motive or further details about the relationship between the two people involved, Right Now Oregon noted.
Charges explained
Martinez-Hernandez faces three felony counts: Attempted Murder in the Second Degree, Assault in the First Degree and Burglary in the First Degree. Under Oregon law, criminal attempts are defined in Oregon Revised Statutes section 161.405, as compiled by Justia. The statute for first-degree assault appears in ORS 163.185, published by FindLaw, and first-degree burglary is set out in ORS 164.225, available through Oregon Public Law.
All three offenses are felonies, and first-degree assault and first-degree burglary are among the more serious crimes under Oregon's sentencing scheme.
What happens next
Officials say the investigation remains active, and they have not released additional details, indicating that local outlets will update their coverage as new information emerges. For now, Martinez-Hernandez remains in the Washington County Jail on the booked charges, and the case is in the hands of county authorities, according to KATU.
