Damon and Devon were stabbed to death with a large kitchen knife in Routier's home, while Routier sustained knife wounds to her throat and arm. Routier told authorities that the crime was perpetrated by an unidentified intruder. During the trial, the prosecution argued that Routier's injuries were self-inflicted, that the crime scene had been staged, and that she murdered her sons because of the family's financial difficulties; the defense argued that there was no reason Routier would have killed her children, and that the case did not have a motive, a confession, or any witnesses. In February 1997, the jury found Routier guilty of the murder of Damon, and sentenced her to death by lethal injection.
