20/20's Elizabeth Vargas discusses tonight's focus on Tim Hennis case

The murder of a Fort Bragg wife and her two young daughters in their Fayetteville home made headlines back in the 1980s. It was a mystery that played out for more than 25 years, including here in Wilmington, as suspect Tim Hennis was found guilty, later acquitted, then tried again after two decades of freedom. Tonight it's the subject of a 20/20 report right here on WWAY.
