JEFFERSON COUNTY • Computers traced to the homes of Fox School District Superintendent Dianne Critchlow and another Fox administrator were used to make nasty allegations about three critics of the district, said an attorney representing those critics in a libel lawsuit.

Dan Herman filed suit in February on behalf of Arnold residents Sam Ferry, Rich Simpson and Michelle Tyler. All have been critical of the Fox School District, which sent them letters in recent years warning them to tone down their behavior or face legal action. They say they have become the victims.

But the defendant in their suit is listed as John Doe because they did not know who made the comments on a website. Now they do, Herman said.

He said the comments had been traced to computers registered to Critchlow’s home address as well as that of Angela Burns, who is married to Dan Baker, an assistant superintendent. Burns is an assistant principal in the district, Herman said. They also were traced to the home of William Brengle, who retired as an assistant principal at Fox High School in 2009 after more than 30 years in the district.
