Man finds hole in wall at business

According to an article in the Flint Journal, burglars left a hole in the wall of a Flint business, which was found on Sunday Oct. 16 by the owner. Among the items missing where 3 computer laptops, a furnace, and a sound system. According to the police report, there is no suspect information. Also there seems to be no information about what made the hole in the first place. I picked this photo because I think it most accurately describes the site the owner would've witnessed as he arrived at his businesses on Sunday. Photo link is here. License link is here. I'm pretty sure I followed everything.
