A 20-year-old Auburn man was charged last month with second-degree rape in the alleged assault in June of a developmentally delayed blind woman for whom he cared at a Renton facility.

Samuel Kiranga Njuguna pleaded not guilty at his arraignment in September. He was released from jail on Oct. 16 after posting $25,000 bail. His next court appearance is Nov. 19.

The 65-year-old victim, who is also deaf, is able to communicate using her hands; she has a 100-word vocabulary.

According to charging documents, she suffered injuries consistent with rape that were discovered by another caregiver. An employee discovered a condom wrapper in a trash can, wrapped in latex gloves, and turned it over to detectives.

DNA samples were collected from all male workers, except for Njuguna. The results cleared those workers.

Njuguna was reached by phone in Portland but he didn’t keep an appointment to meet with detectives at the Renton Police Department. He drove to Las Vegas, Nev., where he attempted suicide and was in a psychiatric ward somewhere.

He was located in a hospital in Las Vegas, where a sample of his DNA was obtained. His DNA matched the sample taken from the condom.
