A Pennsylvania judge on Monday said the statute of limitations barred prosecution of the former mayor of Harrisburg on about two-thirds of the nearly 500 corruption charges filed against him last summer by the state attorney general.

Judge Kevin Hess threw out 305 of the counts against Stephen Reed, 66, who was the Democratic mayor of Pennsylvania's capital city from 1982 to 2010.

"We are pleased with the decision," said Reed's lawyer, Henry Hockeimer Jr. "Judge Hess' ruling disposes of the vast majority - including the most serious - of the charges."

The majority of the 144 remaining counts relate to allegations that Reed stole artifacts purchased for the museum, and kept them at his home in Harrisburg home or in a private warehouse. He has claimed that in reality he was the owner of many of the items.
