According to the Washington County Police, Roper was living with the 62-year-old victim in an apartment in Aloha. She had worked as the victim's caregiver for several years before she left the job.
She later moved back to live with the paraplegic man after she was kicked out of her sister's house for drug abuse, police said.
According to a local TV channel, the woman was involved in an hours-long standoff with the police in the apartment after law enforcement agents were alerted about the assault.
However, Roper was finally taken into custody on an assault charge after the police used a stun gun on her.
