JOLIET, Ill., Feb. 2 (UPI) -- Kathleen Savio's sister testified Tuesday in an Illinois court that Drew Peterson once threatened to kill Savio while holding a knife to Savio's throat.
The Chicago Tribune said the allegation against Peterson was made during Susan Savio Doman's testimony at an evidentiary hearing in Will County Court. Peterson is charged with murder in the 2004 death of his ex-wife.
