FILE - In this Sept. 8, 2014 file photo, Cathy Woods appears in Washoe District court in Reno, Nev. Washoe County District Attorney Chris Hicks plans to announce Friday, March 6, 2015, whether he intends to go forward with the retrial of Woods, who was ordered set free last year after spending more than 30 years in prison for a murder she may not have committed. New DNA evidence recovered from the 1976 crime scene on the edge of the UNR campus matches that of a former Oregon inmate recently extradited to California to face murder charges in a string of killings in the San Francisco Bay Area during the same period when Cathy Woods allegedly slit Michelle Mitchell’s throat in Reno.
