An appeals court ruled that a man being held in Rhode Island on a murder charge was to face federal charges, and a possible death sentence, despite efforts by Rhode Island’s governor to keep the case under state jurisdiction, according to court documents. Jason W. Pleau, who allegedly robbed and fatally shot a gas station clerk in Woonsocket, R.I., had been stuck in custody limbo between Governor Lincoln Chafee’s refusal to release Pleau and federal authorities effort to charge him.
