Federal prosecutors say they don't think a retired U.S. Marshal was telling the truth when he took up for Jeffrey MacDonald, the military doctor convicted of killing his wife and two children 38 years ago.
The News & Observer of Raleigh reports Saturday that prosecutors argued in papers filed this month that Jim Britt never drove to South Carolina to bring a key witness to MacDonald's 1979 murder trial.
Britt died last month. He came forward in 2005 saying he heard a prosecutor coerce that witness to lie in MacDonald's trial. MacDonald's recent appeal was based Britt's statements.
MacDonald, a former Fort Bragg Army surgeon, is serving three life sentences for the murders of his pregnant wife and two daughters. The story produced the best-selling book and television miniseries "Fatal Vision."
