The Eastburn family murders were the murders of Kathryn "Katie" Eastburn and her daughters, Kara and Erin, which occurred in Fayetteville, North Carolina in May 1985. In 1986, United States Army Sergeant Timothy Hennis was tried and convicted for the three murders. In 1988, Hennis' conviction was overturned on appeal and he was acquitted the following year. In 2006, the Cumberland County Sherriff's Office obtained DNA evidence linking Hennis to the crime. Despite the Fifth Amendment's Double Jeopardy Clause prohibiting retrials after acquittals, the United States Army was able to initiate prosecution and trial proceedings against Hennis under the dual sovereignty doctrine. In 2010, Hennis was tried and convicted by an Army court-martial for the triple murders and sentenced to death.
