I'm sorry to hear about your loss, but please, never ever ever put anything of value in checked bags. Checked luggage is strictly for clothes and other items you don't care about losing.
Baggage theft (by handlers and others) is rampant throughout the world, plus there is always a risk of damage. All electronics, valuables, medication, etc., should only be carried with you.
It's not much help for what happened now, but I second the suggestion for going the insurance route. Neither the airline or TSA will be interested in hearing about lost valuables in checked luggage....they will just state those items shouldn't have been in there
