CONOWINGO, Md. (AP) — Authorities say an 84-year-old Maryland man has been charged with fatally stabbing his older brother.

Cecil County Sheriff’s Office spokesman Lt. Michael Holmes says deputies found the body of 87-year-old George Carlton Richardson Sr. on Monday night.

Holmes says the body was in the backyard of the Conowingo home of Silas D. Richardson.

Deputies say Silas Richardson went to his brother’s home Monday in Neptune Township, New Jersey, and told the man’s girlfriend that George Richardson had died but he gave no details. Deputies then went to Silas’ home to check things out.

Holmes said the deceased brother had gone to the Maryland home to help out after the younger brother’s wife died last week. It was unclear when he arrived.

Silas Richardson is charged with first-degree murder.
