According to information from the initial investigation by the Bradley County Sheriff’s Office, Hallmark, 65, and his stepson, Richard Lee, 57, were involved in a “domestic confrontation” when Hallmark shot Lee three times.
The two were at their 3rd Street N.W. home at the time of the shooting, reports said.
Hallmark was originally charged with aggravated assault (domestic) and held without bond pending arraignment in Bradley County General Sessions Court.
A jury trial held in Bradley County Criminal Court was held March 1 and a jury found Hallmark guilty of a lesser offense of attempt to commit voluntary manslaughter.
Sentencing was handed down late Monday evening.
Bradley County Criminal Court Judge Carroll Ross sentenced Hallmark to 90 days in the Bradley County Jail and three years’ probation.
Jerry Hoffer represented Hallmark in the case.
The prosecuting attorneys for the 10th Judicial District Attorney General’s Office were Mac McCoin and Cynthia LeCroy Schemel.
