Iowa Man Convicted of Killing Two Stepdaughters During Satanic Ritual

An Iowa man has been found guilty of killing his two stepdaughters during a ritual from a satanic bible.

Lawrence Harris Sr., of Sioux City, was convicted Thursday on two counts of first-degree murder in Woodbury County District Court.

Sentencing is scheduled for Feb. 18. The convictions carry a mandatory sentence of life in prison.

Ten-year-old Kendra Suing and her 8-year-old sister Alysha Suing were found stabbed and strangled on Jan. 6, 2008. Authorities were responding to a fire at their home.

Harris told police that he was performing "some strange ritual" that had gone bad. Prosecutors have said he practiced Satanism and that the killings were part of a ritual.

A message left Thursday for Harris' attorney wasn't immediately returned.
