CENTENNIAL, Colo. (AP) — Prosecutors are methodically building a case that James Holmes knew right from wrong when he planned and carried out the deadly Colorado theater shootings. After a month of testimony from victims and investigators, prosecutors this week shifted to Holmes’ mental state. They hope to convince jurors he should be convicted and executed, not sent to a mental hospital.

Holmes has pleaded not guilty by reason of insanity to the 2012 attack, which killed 12 people and injured 70.

On Thursday, prosecutors plan to question a state-appointed psychiatrist who examined Holmes. District Attorney George Brauchler has already told jurors the doctor concluded Holmes was legally sane.

Earlier this week, prosecutors showed jurors a notebook Holmes kept that included a map estimating how long it would take police to respond to an attack.
