RUTLAND, Vt. -- The second day of testimony in the trial of a man accused of killing a University of Vermont student from Northern Virginia was postponed Friday because he was ill.

Brian Rooney, 37, of Richmond, Vt., charged with raping and killing Michelle Gardner-Quinn, 21, of Arlington, was taken to Rutland Regional Medical Center after vomiting.

After returning to court, a pale Rooney said he felt better. But when Judge Michael Kupersmith asked him if he would be able to focus on the trial, he said he was worried about getting sick in court.

"If I'm feeling like I'm going to be sick, then I'll be focused on that," he said.

"I don't feel secure right now," said Rooney, who then apologized to the court.

Kupersmith said he suspected Rooney was suffering from a stomach bug, telling him there was no need to apologize.

He postponed the resumption of testimony until Monday -- if Rooney's condition improves.
