COOS BAY, Ore. (AP) — Authorities say a Coos Bay man has been arrested in the death of his 89-year-old grandmother. The World reports District Attorney R. Paul Frasier said 32-year-old Kevin Yates is facing charges of second-degree murder after Teclutsa Margaret “Margie” Sause was found dead Saturday at a Coos Bay home. Frasier says the Coos County Sheriff’s Office received a 911 call reporting a woman had been killed at a residence. When deputies arrived, they found Sause dead inside. Frasier said evidence showed Sause was murdered. Frasier says Yates was arrested at the scene and taken to the Coos County jail. It wasn’t immediately known if he has a lawyer.
