Cessna 340: twin propeller, low-wing, 6-seat airplane.
At an uncontrolled airport, my first suspicion would be that the Cessna 152 was in a standard VFR pattern and the Cessna 340 was shooting a direct in IFR approach. High-wing pilot already in the pattern doesn't see low-wing descending due to the wing. Low-wing twin pilot that's descending doesn't see the 152 below it.
Departed a VFR pattern more than once for a hot-head shooting an IFR approach that didn't want to wait in the queue or circle around.

The 340 may have run over the 152 on final for the same runway. But there are two runways. Perhaps the 152 was practicing crosswind take offs and landings, and the 340 was using the headwind runway. They had to hit fairly low to the ground for the 340 to slide across the tarmac and into that hangar.
