Kiyoko Nagumo

Kiyoko Nagumo was an elderly Japanese-American woman living in San Atanasio, California. One day she became concerned when her sister, Eiko Ryan, failed to show for lunch. She telephoned her and when she didn't answer, Mrs. Nagumo came to her apartment at Marseille Gardens. She had the property manager unlock the apartment door and the two found her body. Mrs. Nagumo immediately called 9-1-1 and waited for police to arrive.

Two uniformed police officers responded and a patrolman named Pete did a preliminary interview with Mrs. Nagumo. She was then questioned again by Lt. Colin Ferguson when he arrived on the scene.
