French judicial officials have named three investigating judges who specialize in financial, public health and organized crime cases to lead a criminal probe of the Germanwings plane crash that killed 150 people.

Marseille Prosecutor Brice Robin disclosed the names of the three judges Friday, two days after announcing an independent inquiry on charges of involuntary manslaughter linked to the March 24 crash of Flight 9525 from Barcelona to Duesseldorf.

Investigators believe co-pilot Andreas Lubitz purposely crashed the plane.

Financial affairs specialist Anne Tertian, public health specialist Annaick Le Goff and organized crime specialist Marie Grandjouan will seek to determine whether any other person, company or public agency might be liable.

The three women have worked with a branch of the Marseille court that focuses on group accidents.
