FORT ANN, N.Y. (AP) — Authorities say they've charged a New York man with strangling his 95-year-old grandmother inside the rural upstate home they shared.

The Washington County Sheriff's Office says 50-year-old Kevin Gonyea (GAHN'-yay) was charged Wednesday with second-degree murder in the death of Leona Twiss.

Police say Gonyea and his 35-year-old wife Melissa reported finding Twiss dead Sunday night in the family's home in the town of Fort Ann, 55 miles (88 kilometers) northeast of Albany.

Officials say an autopsy determined Twiss had been strangled with a towel. Police say Melissa Gonyea was charged with hindering prosecution and tampering with evidence because she disposed of the towel.

Both the husband and wife are being held in the county jail. Their lawyers didn't comment on the charges.
