Sara Krueger and Ryan Warner Convicted of First Degree Torture Murder

Napa County District Attorney Allison Haley announced today: Just before 12:00, Sara Lynn Krueger, aged 27, and Ryan Scott Warner, aged 29, were both convicted by separate Napa County juries. Both defendants were found guilty of first degree murder, the special allegation that the murder involved torture, and assault on a child causing death. The Honorable Judge Francisca Tisher presided over this six week jury trial in the Napa Superior Court.

Both defendants were found criminally responsible for the death of Ms. Krueger’s three year-old daughter, Kayleigh Slusher. On February 1, 2014, Kayleigh was found dead in her apartment with 41 visible injuries and multiple internal injuries indicative of physical child abuse and torture. The case was investigated by the Napa Police Department and led by Detective Andy Hess. The excellent investigation led to the arrest of both Ms. Krueger and Mr. Warner.

The case was prosecuted by Napa County Deputy District Attorney Lance Hafenstein, Deputy District Attorney Kecia Lind and District Attorney Investigator Leslie Severe. This team worked tirelessly to advocate for Kayleigh and bring her justice. Deputy District Attorney Hafenstein stated: “I am very grateful for both juries’ verdicts in this case. This was a difficult and traumatic case to see and listen to, and the jurors were always attentive and considerate of the evidence presented. These verdicts are a message to our community that our children are to be treated with love, patience, and respect. They are our future. What was done to Kayleigh Slusher by these two defendants was simply inhuman. She was taken from us much too soon.”

Deputy District Attorney Lind stated: “We are extremely pleased with the juries’ verdicts, and grateful for the time and consideration they put into their decisions. This was a difficult case for all of those involved. We would like to especially thank the Napa Police Department for the countless hours of investigation they put into this case, as well as to each member of the jury who was undoubtedly emotionally affected by what they had to hear throughout the pendency of this trial. Kayleigh Slusher did not deserve the fate she met at the hands of those who were supposed to protect her. We are relieved that justice was served today, and hope that the result of this trial will help to bring some closure to those who knew and loved her.”
