Four of 10 Americans arrested while trying to bus children out of Haiti without proper documents or government permission, from left to right, Drew Culberth, 34, of Topeka, Kansas, Nicole Lankford, 18, Carla Thompson, 53, and Corinna Lankford, all of Meridian, Idaho, move their bags as they ride in a Haitian police truck from court to jail Friday in Port-au-Prince.

Port-au-Prince, Haiti ? Ten U.S. Baptist missionaries charged with child kidnapping returned to jail Friday after failing to persuade a judge to grant them provisional release pending the outcome of their case, their lawyer said.

The weary looking Americans were led one by one into the back of a police van after spending half the day at a courthouse in the rubble-strewn capital. A judge scheduled three more days of hearings next week, starting Monday, defense attorney Edwin Coq told reporters.

Haitian officials at the court declined to answer questions from journalists about the case. The missionaries did not respond to questions and Coq said they had been ordered by the judge not to discuss their case.

The lawyer said that at least nine of the Americans — all but the group’s leader, Laura Silsby — clearly did not know they lacked the proper papers to remove 33 children from Haiti following the devastating earthquake and they should be immediately released.

“They came to Haiti to help. They came in solidarity,” he said. “It is scandalous that they are being detained.”
