Authorities investigating the sniper shootings believe the two men they are questioning lived for several years in the Pacific Northwest, mainly in the Seattle/Tacoma, Wash., and Bellingham, Wash., areas. Police in Bellingham described John Lee Malvo as "quiet" and say he spent a lot of time in the library at the high school there. Officials say he and John Allen Muhammad moved to Clinton, Md., early last year. Muhammad is a veteran of the Gulf War and was based at Fort Lewis, Wash., in the 1980s. Muhammad has been married and divorced twice. NPR's Robert Smith talks to Jacki Lyden about the latest background information from Seattle.
