The tribute was held at the San Diego Police Officers Association building in Kearny Mesa in conjunction with National Crime Victims' Rights Week, which began Sunday. It is held annually to promote awareness of victims' rights and honor crime victims and survivors, according to the Office for Victims of Crime.This year's National Crime Victims' Rights Week theme is "Extending the Vision: Reaching Every Victim."Organizers planned a slide presentation honoring victims and a candle lighting.U.S. Attorney Laura E. Duffy will be the keynote speaker at the tribute. Crime victim speakers include Taya Chase, whose car was struck by a hit-and-run driver in 2009; Elsie Lott, mother of Tamara Henderson, who was shot to death by her husband last year and Rita and Dick Moore, parents of Andy Tan Tai Moore, a college student found dead in his San Diego apartment in September 2000."We are just another grieving family, but we offer hope to other families because somehow life goes on," said Rita Moore. For the Moores, the candlelight vigil is one more opportunity to get the word out in hopes the killer of their son Andy might surface. "It's been almost 12 years it's unsolved," said Rita Moore. "We ask ourselves daily how could it be that first of all, someone could do this." At the time of his death, Andy Moore was working as a chef in the Gaslamp Quarter and attending City College. Memories of what came after his death still cause his mother to break down to this day. "We slept on his grave the night he was buried because I couldn't bear for him to be alone," she said. "We visited the cemetery every day for the first two years." But after twelve years full of grief, there is zero closure. The Moores said they have tried everything and after all these years, they are still coming up empty handed. "That person who did it for 12 years now has been out here," said Rita Moore. The Moores continue to offer a $56,000 reward for any information leading to an arrest and conviction in their son's death.
