Retraction and correction
Control Engineering , in the July 2009, North American print edition, Inside Process section, in an article titled, “Addressing SIS Cyber Security; Is it First or Last?” erroneously stated that Michael Keehn, a former project superintendent at the Tehama Colusa Canal Authority (TCCA) in Willows, California, was convicted of tampering with the TCCA computer system and sentenced to 10 years in federal prison. Keehn has not been convicted of, nor sentenced in, any crime. Keehn, who designed the TCCA control system, was indicted on a count of unauthorized access. He denies all wrongdoing and has pleaded not guilty. His case is expected to go to trial in 2010. Control Engineering regrets the error.
