Bicycle detail

My bike (Black 2020 Schwinn Axum Mountain Bike, 29'' wheels, Large 19'' frame with shimano mt200 brakes) was stolen on February 16 sometime between 3:30 pm and 7:10 pm. I parked the bike at 3:30 pm by the University of Colorado Boulder SEEL Laboratories - MacAllister Research Center, Boulder, CO 80303, in the covered bicycle parking and that's the last time I saw it. When I came back to get the bike at around 7:10 pm, It was not there and I could find part of the U-lock I used to lock the rear wheel and the frame into the bike rack (The first U-lock was around the back wheel, the frame and the bike rack.). The lock had signs of force as you can see in the attached pictures. From the pictures of the lock, you can also infer that the lock was cut using Bolt cutters. The bike was also locked using a second U-lock on the front wheel and the frame, but I couldn't find parts of the second U-lock, meaning that the bike was probably loaded in a car with the front U-lock intact.
