WASHINGTON – The Los Alamos nuclear weapons laboratory in New Mexico is missing 69 computers, including at least a dozen that were stolen last year, a lab spokesman said. No classified information has been lost, spokesman Kevin Roark said. The watchdog group Project on Government Oversight on Wednesday released a memo dated Feb. 3 from the Energy Department's National Nuclear Security Administration that said 67 computers were missing, including 13 that were lost or stolen in past 12 months.
