have someone pull on the release handle while someone else is pulling/wiggle the e-brake cable at the rear by the wheels to see if they will release. you can try spraying penetrating fluid on the cables and wiggle trying to free them up. if not then they may have to be cut and freed up so the rear brakes are not locked on.
