Teri Knight sits at her home in Hillsboro, N.H. Friday Dec. 2, 2005. Knight, the mother of murdered children Sarah and Philip Gehring says authorities told her the bodies discovered in Ohio had duct-tape crosses by them. The children's father, Manuel Gehring, said he killed them in 2003 and buried them somewhere between Pennsylvania and Iowa along a stretch of interstate. He later took his own life.
