stolen Trek 820

Bikes to a buddy’s house, placed it on a porch, stupidly didn’t lock it when I went inside to get a drink, came right back out and it was gone. It’s couldn’t of been even 5 minutes. The only main identification in the gray box underneath the seat. It’s for a toddler seat to attach too. I can file a police report this afternoon. The bike store it was purchased from is closed on the weekends. I’ll call Monday and hopefully have more information. It’s not letting me upload the proper day/ time. It was Saturday 4/18 @ 1030p
