The brother of a Medford woman who went missing two years ago announced a $12,000 reward Thursday for information that could lead law enforcement to his sister, who was 71 when she went missing. Paul Estey, whose sister Diana disappeared from her home in November 2016, contributed $6,000 to the reward, matching $6,000 in contributions from friends, family and other Medford residents that Kent Black, a Medford resident and friend of Diana Estey’s, raised through a GoFundMe campaign.
