Replying to Backpack Taken from PCMR

Someone lifted our back pack from the bottom of 3 kings at PCMR today between 3 and 4. Black cheap backpack with the canyons logo on it. It had car keys, a gopro, and beers in it. there were a few black packs there so maybe someone just grabbed the wrong one. If you know anything about it let me know! reward will be provided. car keys suck to replace and it's my buddy's ride to work on monday. gopro had some shot i need for a project too. Thanks!
