Prosecutors allege Jones killed the children in August of 2014 before dumping the bodies in another state. Prosecutors are pursuing the death penalty for Jones.

Jones has pleaded not guilty by reason of insanity in the case.

His guilty plea would allow one of four possible outcomes in the trial: guilty, guilty by reason of insanity, not guilty by mental defect, or not guilty.

If found guilty, the death penalty would not be automatic. Jurors would then be asked to consider extenuating circumstances and could sentence Jones to life without parole rather than death.
