Four years ago this week, Amanda Tusing was found dead in a ditch in Craighead County. The 20-year-old woman had last seen driving to her home in Dell from her fiance`s home in Jonesboro. Her car had been found undisturbed alongside Arkansas 18 near Monette, miles away from where her body was found. An autopsy revealed that the woman drowned, but investigators also noted a bruise on the side of Tusing`s head. Craighead County Sheriff Jack McCann says his department is still investigating. He said new evidence is developed from time to time, but none has yet led to an arrest. Tusing`s body was exhumed earlier this year, but officials said that did not lead to further evidence. The young woman`s mother, Susan Tusing, says she hopes people remember her daughter and that someone will lead police to the killer.
