stolen 2008 Trek EX8

This is updated: I found my serial number: Someone just stole my Trek EFX7 Fuel Mountain bike (green and white) from my driveway, along with Don's white North Rock mountain bike! We were loading up our car and went inside for 5 minutes to get more stuff and when I walked out, I saw a large white male in a royal blue sweatshirt on MY BIKE riding out of my driveway! I screamed "they're stealing our bikes, they're stealing our bikes" and then the other male rode off on Don's bike. Don chased by foot and I hopped in the car to chase them. But they got away. Cops came nearly immediately (surprisingly!) and took a report and helped us look…to no avail.
