stolen 2013 Republic Dutch

I was at home with my Fiancee watching TV when I heard the bell on my Fiancee's bike ding. I ran to the back of the house where we had them secured and they were missing. I immediately jumped in my car and searched the neighborhood for hours trying to find who could have taken them. They could have possibly been thrown into a vehicle. Both bikes are from the company Republic Bike and one of them is a single speed with a white frame, orange tires, blue rims, and curved handlebars. The other bike is a beach cruiser type bike with a white frame, cream tires, red rims and red handles, with straight bars and a square metal basket on the front. This happened behind our house that is in an alley in Golden Hill behind the Turf Club and Krakatoa coffee house.
