A man convicted of murdering his own grandmother in 2017 will stay behind bars. WNYT reports Kevin Gonyea asked an appellate court to throw out his conviction for strangling 95-year-old Leona Twiss with a towel. Gonyea argued his defense counsel was ineffective when he pled guilty to murder in 2018. The appellate court disagreed – ruling Gonyea’s contention was without merit.
