BOSTON (AP) _ A former probation officer pleaded guilty Monday to stealing two wills signed by baseball Hall of Famers and selling them for more than $15,000.

Joseph Schnabel, 56, of Pembroke, pleaded guilty to two counts of larceny over $250. He was sentenced to a year of probation and fined $5,000.

Schnabel, who resigned before he was charged, must also pay back the buyers of the stolen wills and return payments to the purchasers of similar documents he admitted stealing.

Prosecutors said Schnabel, a probation officer for 15 years at Suffolk County Courthouse, stole the two Hall of Famer wills from the courthouse where he worked in 1996. The documents were kept in the registrar's office.

One document was signed by George Wright, a player for the Cincinnati Red Stockings in the late 1800s. The other was signed by Thomas Connolly, an umpire in the 1920s. Both were elected to the Hall of Fame.

``Stolen bases are legal in baseball, but stealing documents from baseball's greatest stars is a crime,'' said Richard Iannella, Suffolk County's register of probate.

Several stolen papers, however, are still missing, including the wills of players Sam Curran, ``Gentleman George'' Haddock, Jackie Manning, Miah Murray, ``Buck'' O'Brien, Jack Slattery, Tom Smith, Denny Sullivan and Hall of Famer Thomas McCarthy.

The discovery of the missing documents led authorities in other parts of the country to realize they had experienced similar thefts.
