Storage Shed is Wrenched
In a perfect world, this person would have used a chain to loop through the latches and then secure the chain with a lock so no one could get into their storage shed. But they didn’t have a chain on hand, so they improvised by drilling a hole through a wrench and then sticking the wrench between the latches on the doors. And to ensure that no one could slip the wrench out, they stuck a lock in the hole on the wrench.
