Aurora suspect James Holmes was 'relaxed' during arrest
The man accused of killing 12 people and wounding 58 at a cinema in the US state of Colorado in July was "relaxed" when arrested, a court has heard.
Police Officer Jason Oviatt described James Holmes, 25, as "detached" during testimony at a pre-trial hearing.
The hearing, due to last all week, will establish whether the prosecution's case is strong enough to go to trial.
