A human-trafficking charge against a Saudi princess was abruptly dismissed Friday after prosecutors were unable to support claims by a Kenyan maid who said she had to escape from her employer's condominium after having her passport taken and being forced to work long hours for meager pay. The announcement came during what had been expected to be the arraignment of Meshael Alayban, 42, on the felony charge punishable by up to 12 years in prison.
