The man accused of shooting a Muskingum County sheriff's deputy to death says he is not guilty. 27-year-old Henry Hager's lawyer entered the formal plea in Muskingum County Common Pleas Court Wednesday morning. Last week Hager was indicted on one-count of aggravated murder with 3 death penalty specifications in connection with the death of Muskingum County Sheriff Deputy Robert Tanner Jr on January 8th. During the arraignment Hagar's attorney Jon Schumacher reserved the right to additional not guilty pleas. Hagar is being held in the Franklin county jail.
