In an editorial for The Philadelphia Inquirer, Dr. Katherine Ramsland, assistant professor of forensic psychology at DeSales and an expert on serial killers, addresses the question, "How can a serial killer live among us, undetected, for years?" The recent arrest of Dennis L. Rader, the BTK (Burn, Torture, and Kill) killer in Wichita, Kansas, who was a family man, Cub Scout leader and church member, shows that such people can live among us easily. According to Ramsland, serial killers blend in because they're the type of person who can go through the motions of ordinary living and yet act out against others without giving him- or herself away. She describes them as morally deviant but not obviously deranged because they can hide their deviance behind a bland, everyday manner. These people are, in short, psychopaths, says Ramsland.
