The disciplined employee is in addition to two department investigators who lost their jobs for allowing other child pornography cases to languish.
Department spokeswoman Dana Brueck tells WKOW-TV that a member of the Division of Criminal Investigation's support staff didn't promptly address a tip. In February, Christopher Kosakoski of Milwaukee was charged with 13 child pornography counts. But DOJ officials have conceded a tip from a national hotline about Kosakoski's potential downloading of child porn came to DOJ three years ago.
Brueck says the employee was disciplined. She would not identify the employee, the employee's job title or how long the employee has worked for DOJ.
