CENTENNIAL, Colo. A police officer responding to the deadly Colorado theater shooting says he asked James Holmes twice whether he had an accomplice.
Officer Justin Grizzle says all he got was "self-satisfying offensive smirk."
Another officer testified that Holmes said at a different time he was the only shooter.
At a hearing on Tuesday, officers testified that screaming and bloodied victims were still fleeing as they handcuffed and searched Holmes.
The hearing is about whether statements Holmes made before he was read his rights can be used during his trial next year.
Police say they had to find out if someone else was involved in the attack that killed 12 people. Prosecutors contend the questions were legal under a public-safety exemption to the Miranda rule.
