One of the most sensational and infamous murder cases in modern U.S. history is returning to a courtroom this week.
A federal judge in Wilmington, North Carolina, will begin hearing testimony Monday morning on whether Jeffrey MacDonald, the former Green Beret doctor convicted of killing his family, should get a new trial.
MacDonald, 68, is expected to be present at the proceedings. He has long said that a group of hippies beat and stabbed to death his wife and two young daughters in their Fort Bragg, North Carolina, home on February 17, 1970.
MacDonald told investigators that he was at home, sleeping on a couch, when he heard screaming. He awoke to find three men and one woman, whom he described as having blond hair and wearing a floppy hat. They chanted "kill the pigs" and "acid's groovy" before attacking him, MacDonald said. He suffered two stab wounds and a collapsed lung.
