PORTLAND, Ore. (KOIN) – A man who allegedly attacked his elderly mother and her caretaker is now being charged with second-degree murder after the caretaker died from her injuries.

Washington County Sheriff’s Office deputies reportedly responded to a 911 call on Sunday, Nov. 13 on the 9200 block of Midea Court in unincorporated Washington County.

According to WCSO, 44-year-old Benjamin Hershel Ritchie had attacked his 79-year-old mother and her caretaker, 57-year-old Clare Krill. Deputies reported finding Krill unresponsive after Ritchie allegedly hit her with a side table, causing severe injuries to her head and face.

Deputies say that medical personnel transported Krill to a local hospital in serious condition. Detectives from the Violent Crimes Unit were also on hand to help with the investigation. Krill was pronounced dead on Tuesday, Nov. 22.
