FBI seeks public input on possible Vallejo serial killer ( link ) Sohn said that just before he died, Anderson confessed during a 51/2-hour interview with two FBI agents, one a profiler, that he was responsible for at least six more victims, including Pinole's 7-year-old Amber Swartz-Garcia. Amber's mother was involved in the searches for Xiana and Midsi. Anderson, however, was known to be less than truthful, so, agents are hoping to determine the validity of his claims and offer "closure" to loved ones, Sohn said. "This case has been open since the interview in jail with him in November 2007," Sohn said. "Initially, the goal was to find out if he had anything to do with the disappearance of Amber Swartz. But in the course of the interview, he admitted to six others he allegedly kidnapped and killed, and we have open cases on these while we try to figure out if these are real." [...] Xiana Fairchild, who vanished Dec. 9, 1999, and whose skull was found in early 2001 in Los Gatos, may have been Anderson's eighth victim, if his account of others is accurate. "He was looking for vulnerable victims that he could take advantage of; an opportunist," Sohn said. "We're hopeful for any tips. We hope someone will recognize some of the descriptions; that they might trigger a memory and produce a lead, so we can bring some closure to families." The FBI urges anyone with information on the identities of any of the alleged victims to call the FBI tip line, at 800-225-5324.
