Sorry to hear this Eric, I've almost exactly the same kit and this is my biggest fear.

20 years ago, When I was 18 [and had a Zenith camera with 50mm lens] I was away for at a concert. The night before it I was offered a huge camera bag with 2 Olympus slr bodies, 2 zooms, 4 primes, flashes and film, all for the price of a few rolls of film. I phoned the police and the guy arrested in minutes. The gear returned to the photographer who was with a national newspaper. I hope you have a happy ending also.
