Well that should be a really simple one but you need the car in front of you, a wiring diagram and a test meter.

Job #1 first would be fully charge the battery.

Then check for voltage where it should/shouldn't be etc.

A specialist who can't figure out why a car won't crank?

You've omitted how the fault first manifested but I guess the first step is figuring out if it isn't trying to crank or if the engines seized.

Did you pay anything for them to go "huh?"

It sounds like the garage simply hasn't diagnosed the issue, did you tell them to keep looking until its diagnosed or have they charged you for an hour, looked at a number of things, eliminated them then stopped work?
