"He seemed very detached from it all," Oviatt said.
Holmes, his pupils dilated, sweating and smelly, didn't struggle or even tense his muscles as he was dragged away to be searched, Oviatt said.
Police would cut off the body armor he wore and learn from him about the explosive booby-trap at his home.
Police described a strange scene in the interrogation room -- Holmes sitting in his underwear, T-shirt and white socks after police had had cut away his body armor -- making puppets of the paper bags officers had placed over his hands to preserve gunpowder evidence, according to Appel.
Holmes played with his polystyrene drinking cup as if it were a piece in a game. Appel said. Then he removed a staple from the table and tried to stick it in an electrical outlet, the detective testified.
Asked by a defense attorney whether he had ordered a blood test for Holmes, Appel said he had not.
"There were no indications that he was under the influence of anything," he said.
