1996 Other Saturn Models will not turn

Aloha everyone! Here is my dilemma....
96 Saturn sl2 4 cyl 89k 2 door coupe. Car was running fine throughout the day. Engine started with no probelms. Sushi here - starbucks there - even the beach. Went to the store later that evening and car would not start. Lights, radio, gauge displays, ac blower, and horn fine-external lights and signal operating fine. Had tow truck jump still car would not respond to jump. Next day, had battery changed, all internal and external lights still fine and internal accesories operating but engine still will not turn. Only recent repair was 6 months ago had the starter changed.
