The 10 inmates who broke out of a New Orleans jail in a stunning overnight escape last week used electric hair trimmers with multiple clipper blades to help cut their way through the cell walls, a source with direct knowledge of the investigation told CNN.

Weeden faces one felony count of accessory after the fact, which carries the possibility of a fine up $500 and up to five years in prison, according to the state police release.
