PITTSBURGH — Federal agents raided at least two homes and took three Western Pennsylvania men into custody — one of them as he left church — after seizing an unknown number of weapons.

Prosecutors were seeking to keep the defendants jailed until trial, but would not say why. Indictments returned last week remained under seal.

Morgan Jones, of Lucinda, Marvin E. Hall, of Rimersberg, and Perry Landis, whose address was not immediately available, appeared before a federal magistrate on Monday and remained jailed until a detention hearing Wednesday. A fourth man was set to appear before a federal magistrate in Johnstown, but prosecutors would not release his name.

Special Agent William Crowley, spokesman for the Pittsburgh FBI office, would not say what was seized during searches at Jones' and Hall's properties. But Jones' wife and Hall's girlfriend told The Associated Press that guns were taken from both locations during Sunday's raids.

Neighbors saw a plane, bomb squads and dogs on Morgan Jones' property in Clarion County on Sunday, The Derrick of Oil City reported.

At the detention hearing, prosecutors must present arguments and evidence about why the men should stay in jail until they stand trial. By law, the government must prove the men are dangerous, a risk to flee prosecution, or both; prosecutors did not say why they planned to seek detention.

Hall's girlfriend, Melissa Huet, 34, was also indicted but was not in custody Monday. She told The Associated Press that Hall is 50. The other men appeared to be older than Hall.

"They're a bunch of old men who sit around and talk and don't do anything," Huet said, when asked what she knew about the charges before the hearing. She said an informant has given the government information about the men.

Jones' wife, Donna, said her husband is a gun collector, not a criminal.

"I think the charges are going to be exaggerated," she said, accusing federal agents of overkill for arresting her husband as he came out of church.

"I believe going and taking him at church is nothing but showboating," she said. "All they had to do was knock on our door."
