ROCHESTER, N.Y. -- The suspect in the 2003 Xerox Federal Credit Union bank robbery and homicide in Webster is now charged with possession of a firearm.

Richard Wilbern appeared in federal court Monday morning, where new details emerged from an unsealed indictment from the criminal complaint in the case.

Documents say when Wilbern went to the FBI to file a complaint he told authorities he keeps his belongings in his girlfriend's garage.

A search of the home on September 27th revealed a black ski mask, notebook and semi automatic rifle amongst Wilbern's belongings in the garage.

Wilbern, a convicted felon for a 1980 robbery, was charged with possession of a firearm for the gun recovered.

Wilbern's attorney says he doesn't know if the firearms have undergone forensic testing or are linked to the Xerox shooting.

"We do not think it is related, but we will wait and see we have not had a chance to review the complaint, said Bill Easton, Wilurn's attorney.

Federal authorities did not make a ruling Monday on whether they will seek the death penalty for Richard Wilbern. That can take as long as 90 days to decide.

Wilbern, a former Xerox employee, is accused of robbing the credit union and fatally shooting Raymond Batzel, who was a customer in the bank at the time.

Raymond Batzel's family was in federal court today. They say they're stunned but not surprised at the latest charge against Wilbern.

"He was probably prepared to do more damage someplace elsewhere at some time, who knows," said Diane Powers, Batzel's sister.

Batzel's family has no idea if the seized firearms had anything to do with the deadly Xerox shooting.

"There is always hope for just one tip to solve your family's crime or the loss of a loved one and we will all stand together until the very end," Powers said.

He was arrested in September, 13 years after the shooting. Prosecutors say his DNA matches samples found at the crime scene.

He is scheduled to return to court December 15th.
