Laura Silsby, the last U.S. missionary behind bars in Haiti for arranging to transport 33 children out of the country, has been set free.

A Haitian court convicted her Monday of arranging for illegal travel to take the children out of Haiti without proper paperwork.

But in a surprise decision, the judge said her time has already been served and released her.

Silsby and nine other members of a missionary team were arrested shortly after the January earthquake.

Charges against the rest of the team were dropped when they were later released.

Silsby is expected to fly home to the U.S. Monday night.
