Unless she is used to driving it, she probably did what my dad did first time he went off on a road trip - he thought he was turning the headlights out by turning the knob full CCW. As you know, that leaves a parking light on. My step-mom did it not two weeks later. Now they know better......

Have her hook it up to a charger overnight and try again tomorrow. Make sure whatever she left on is turned off.

If that isn't the problem, have her put a smallish C-clamp on each of the battery posts (after cautioning her about shorts!) and clamp 'em down. If it then starts, it's the battery terminals at fault.
