Jury selection is scheduled to begin Tuesday in federal court Little Rock in the trial of a lawyer from Pocahontas accused of mailing a poisonous snake. Bob Sam Castleman and his son, Robert Jerrod Castleman, both of Pocahontas, were each indicted for mailing a threatening communication to Albert Coy Staton. Police said the families had an ongoing dispute. Staton`s wife opened the parcel with the copperhead but was not hurt. A Randolph County sheriff`s deputy shot the three-foot snake. Opening statements could be this afternoon. The indictment was handed up last summer, and authorities say the snake was mailed in September 2002.
