Jurors Shown Chilling Footage in Boulder Shooting Trial

Ahmad Alissa's trial reveals new harrowing details as survivors testify and mental health evaluations are scrutinized.

Jurors viewed full security footage of Ahmad Alissa's rampage through the Boulder King Soopers for the first time.
Survivor Sarah Chen testified that Alissa shouted 'This is fun' multiple times during the attack.
Alissa faces 55 counts, including 10 counts of first-degree murder and 38 counts of attempted first-degree murder.
Defense argues Alissa, diagnosed with treatment-resistant schizophrenia, was unable to discern right from wrong at the time.
Prosecution focuses on evidence suggesting Alissa planned the attack and was aware of its illegality.
