CENTENNIAL, Colo. (AP) — Officers are testifying about the hellish scene they found inside a suburban Denver theater after the 2012 attack that killed 12 people and left 70 injured.

Three officers said Wednesday they encountered bloody victims, noxious smells and blaring sounds. The gloomy darkness was pierced by bright flashes from a fire alarm.

It was the third day in the trial of James Holmes, who’s charged with murder and attempted murder.

His lawyers acknowledge he was the gunman but say schizophrenia controlled his mind. They want the jury to find him not guilty by reason of insanity, which would commit him indefinitely to the state hospital.

Prosecutors argue Holmes was sane and knew what he was doing was wrong. They want the jury to convict him and sentence him to die.
