The last of 10 American missionaries detained in Haiti on suspicion of kidnapping is facing a new charge.

Judge Bernard Saint-Vil says Laura Silsby has been charged for a newly discovered, alleged attempt to bus child earthquake survivors to the Dominican Republic on Jan. 26.

She already could face trial on kidnapping and criminal-association charges from her group's attempt to take 33 children across the border without permission three days later.

Saint-Vil has added the new charge of "organization of irregular trips," from a 1980 law restricting travel out of Haiti that was signed by then-dictator Jean-Claude Duvalier.

The judge said Friday he has until early May to decide whether to release Silsby or order a trial.
