A federal judge’s decision to overturn an eight-year-old conviction for the high-profile murder of a Manhattan doctor that occurred 29 years ago has presented Manhattan District Attorney Cyrus Vance, Jr. with a difficult choice.

The district attorney must now decide whether to release Darryl Whitley from prison or to retry him within 60 days for the murder of 31-year Dr. John Chase Wood, who was fatally shot during a mugging on his way back to work at Columbia Presbyterian Hospital on the evening of Nov. 2, 1981.
