A Centereach man was sentenced Wednesday to 25 years to life in prison for beating his fiancé’s 90-year old grandmother to death four years ago.
Robert Waters was convicted of second-degree murder in December at Suffolk County court.
Prosecutors said the 24-year-old man fatally beat Florence Troiani after an argument with his fiancé on June 21, 2011.
Judge Fernando Camacho rejected the defence attorney’s argument that Waters suffered a violent seizure brought on by his withdrawal from an anti-anxiety medication, or that Waters was acting under the influence of true emotional disturbance.
His attorney reportedly plans to appeal the verdict.
