stolen 2010 Trek Madone 5.2 WSD

We locked the bikes up behind the church located at 951 East 100 South, and left them there while we left the building. There were two bikes locked up but the bike stolen was not attached with U lock just with. cable. When we returned at approximately 8:45 p.m. we found the cable cut. the area of the parking lot that it was locked in is overlooked by only one apartment building however we are unsure of who could have stolen it. I am reporting this however it is my wife's bike. Thank you.
