stolen 1999 GT Bicycles Mountain Kore

I had just gotten this bike and put it down in my garage while I ran errands so that I could take it into the shop to get the gears worked on... between noon and about 3 p.m. when I returned, it was gone. 1999/1998 GT Mountain bike with a Kore frame - yellow shocks 2 on front and back. Mens metallic blue with black handle bars slight upturn at the ends. 21 gears old shifting system in which you use levers.
