An airline maintenance company was charged by the state with murder and manslaughter Tuesday for improperly packaging oxygen canisters blamed for the 1996 ValuJet crash that killed 110 people in the Everglades.

The company, SabreTech Inc., and three of its employees were later indicted by a federal grand jury on charges of conspiracy, making false statements, and, in the case of the company, failing to train the personnel who handled the hazardous material.
