RALEIGH, N.C. — Two and a half months ago, a Raleigh defense attorney turned over information to the district attorney's office in an unsolved poisoning case. Still, there is no arrest in the murder of Eric Miller, but new prosecutors and a new look at old evidence may help solve the case.

Finding out who killed Raleigh AIDS researcher Eric Miller is Lt. Chris Morgan's primary focus, and he sees it as time well-spent.

"With regard to the Miller case, right now, I feel like we're moving in a positive direction," he said.

In May, under a court order, defense attorney Rick Gammon turned over information to the district attorney from his client, Derrill Willard. Willard killed himself shortly after police searched his home.

Police said Willard was having an affair with Ann Miller, Eric Miller's wife. Ever since, the investigation has focused on her.

"We are actively pursuing the investigation. We added prosecutors and investigators from our office," District Attorney Colon Willoughby said.

Willoughby said two new prosecutors are assigned to the case -- a case which keeps taking new turns.

"Some of the new evidence and developments have prompted us to go back and talk to some witnesses about additional issues and pursue things we hadn't looked at in the beginning," he said.

"You go back to someone you've already talked to a year later, two years later. Something might have changed. You may get additional information," Morgan said.

The district attorney said officials are also looking again at scientific evidence and running it by experts.

"If we bring charges, we want to make sure we have the right person, and we have the right evidence," Willoughby said.

The Wake County grand jury meets every two weeks. They met Monday without discussing the Miller case.
