The suspect in the BTK serial killings has a date in a Kansas courtroom today to hear the charges against him. But it's unlikely that 59-year-old Dennis Rader will be in the courtroom. His appearance before a judge is expected to be made through a closed-circuit television hook-up. Rader is being held on ten million dollars' bail. Authorities say Rader is suspected in ten deaths from 1974 through 1991. A source close to the investigation says Rader had confessed to six killings. It's also been revealed that at the time of the killings, Rader worked for ADT Security Services in Wichita with access to customers' homes. Police have not said if he worked at the homes of any BTK victims. ADT is pledging to cooperate with investigators.
