Updating at story from last week, a legal dispute over DNA testing of supposed evidence against a man accused of setting a southern Illinois house fire that killed four children has been resolved. The Southern Illinoisan reports a judge in Derrick Twardoski’s case has agreed to hiring an expert to oversee testing of eight potential exhibits. Those items include swabs from a gas cap, gas can, a rag, lighter and cigarette pack. Prosecutors had said lab testing may destroy some of the potential exhibits. Twardoski’s public defender objected to that prospect. The 33-year old Twardoski has pleaded not guilty to four first-degree murder counts in the deaths last May in Percy. The fire killed siblings ages 12, 9 and 5-year old twins. Their parents and a 6-year-old escaped.
