At one point, after Christensen denied raising his voice with officers as he denied to them that he had stabbed Vernazzaro, the prosecutor played that section of the tape.
Yesterday, he admitted causing two stab wounds. But he said he had no idea how Vernazzaro got the stab wound on his back.
And at times, Christensen, who showed no emotion during his testimony, challenged the prosecutor.
“Who had the bat?” Buxton asked at one point.
“I think you already know,” Christensen responded.
At another point, Christensen testified that he and Vernazzaro had also exchanged text messages, something police never looked into because they weren’t told about them by Christensen during the interrogation.
“They never asked,” he told Buxton.
During questioning by defense lawyer Ray Buso later in the day, Olingy was asked if she had discussed Christensen’s career goals with him lately.
“He wants to be an attorney,” Olingy said.
