A Dickson County man was charged Wednesday night for the beating death of his wife, whose body was found in their home last month. The Tennessee Bureau of Investigation arrested 23-year-old Morris Lynn “Moe” Long Jr. on a charge of first-degree murder following his release from Vanderbilt University Medical Center Wednesday. A TBI statement says investigators believe Long killed his 21-year-old wife, Ashlee Brook “Sissy” Long, sometime between Dec. 20 and Dec. 22, when her mother and step-father discovered her body in a bed of the couple’s home at 106 Bishop Lane in Burns. Preliminary autopsy results indicate she died from “blunt force trauma.” The day her body was found, police say Morris Long parked his vehicle on Interstate 40 and stepped into eastbound traffic in what was described as a suicide attempt. Long was struck by a truck and had been hospitalized since then. He was arrested following his release Wednesday and taken to the Dickson County Jail. District Attorney Dan Alsobrooks requested the TBI investigate Long’s death because she was the daughter of Dickson Police Department Officer Pat Martin. According to her Facebook page, Ashlee and Morris Long had been married just over a year and had two small children.
