JEFFERSONVILLE, Ind. (AP) _ Jurors have found a southwestern Indiana man guilty of setting a fire that killed his fiancee’s two children.
 
  The jury returned its verdict against Jeffrey Weisheit after deliberating about 90 minutes Tuesday. Prosecutors are seeking the death penalty.
 
  Weisheit was convicted of murder and arson in the April 2010 deaths of 8-year-old Alyssa Lynch and 5-year-old Caleb Lynch at the family’s home near Evansville. 
 
  Weisheit testified on Monday and denied setting the fire, suggesting faulty electrical work he performed might be to blame. But he admitted he stuffed a dish towel into Caleb’s mouth and duct-taped it before leaving the children alone about 1 a.m., while their mother was at work.
 
  Weisheit’s trial was moved from Evansville to Jeffersonville because of extensive media coverage in southwest Indiana.
