BELLEFONTE -- The lead investigator searching for missing Centre County District Attorney Ray Gricar said yesterday that Gricar's girlfriend has requested a polygraph test to clear her name.

Officer Darrel Zaccagni confirmed that the department would work with either the U.S. Secret Service or Pennsylvania State Police to test Gricar's live-in girlfriend, Patty Fornicola, who is not considered a suspect in the case.

"She heard some whispers and asked me when it will be done," he said. "As it looks closer to foul play ... let's get Patty clear of this situation. We want to do it to rule her out."

Although no timetable has been put in place, Zaccagni said he'd like to get the test performed "as soon as possible."

Zaccagni said other members of Gricar's family, including ex-wife Barbara Gray, daughter Lara Gricar and nephew Tony Gricar, have also volunteered to be tested.

"We have no reason [for them to take the test] since they are out of the area," he said. "We start at home, see who has a motive ... and then explore further."

Fornicola, who works as a clerk in the Centre County courthouse and shares a nearby home with Gricar, said she would cooperate with police. She has spoken with officers many times throughout the investigation.

If Fornicola passes the polygraph, police will continue to look at other possible suspects, he said.

"If she would flunk it -- which I wouldn't anticipate -- we'll have to explore it," he said.

"But it's not 100 percent, which is why the Commonwealth Court won't allow it [as reason to charge a suspect]," Zaccagni said.

Zaccagni said Bellefonte police remain in contact with psychic Carla Baron, although she has provided no new information.

He added that civilian searches, some led by nephew Tony Gricar, are ongoing, though nothing concrete has been discovered.

"If we find blood, the police would become involved again," Zaccagni said.

Gricar's last known contact with anyone was a telephone call to Fornicola at 11:30 a.m. April 15 telling her he was taking the rest of the afternoon off from work and driving in his 2004 red-and-white Mini Cooper. At about 6:30 p.m. the following day, Gricar's car was found in a parking lot across from a Lewisburg antique market.

Since his disappearance, Gricar's personal and work e-mail accounts have remained untouched, and according to police, his telephone and financial records have shown no activity.

Police have investigated a number of reported sightings and tips in the case but have so far come up empty-handed. Nothing has been ruled out, including Gricar committing suicide or running off, but Zaccagni said there is a growing possibility of foul play.
