CENTENNIAL, Colo. (AP) — Jurors have reached a verdict in the trial of Colorado theater shooter James Holmes.

The jury found Holmes was guilty of first degree murder.

The panel made its decision Thursday after deliberating for a day and a half.

Holmes has pleaded not guilty by reason of insanity in the July 20, 2012, shootings that killed 12 people and injured 70 others.

Now that Holmes has been convicted, the trial will enter a sentencing phase with testimony about whether he should be sent to prison for life or sentenced to death. Jurors make that decision.

Jurors heard nearly three months of testimony, including heartbreaking and sometimes gruesome survival stories.
