Dzung Ngoc Tu

This undated file photo shows Dzung Ngoc Tu, a Cornell University student, who Michael Ross said he first killed before his arrest in 1984, that ended a three-year wave of attacks that stretched from Connecticut to New York, North Carolina, Illinois and Ohio. He raped most of his victims, and killed eight of them. On Monday, Jan. 24, 2005, a federal judge postponed the execution of Ross after a psychiatrist testified he may not have been competent when he dropped his appeals and asked that he be put to death
