Look at the photo in your post again. Look at the amount of debris that appears “flowing” toward the rear of the aircraft (wires, conduits, plastic snagged on door, door panel. etc.
The plane appears to be missing the rear pressure bulkhead, along with both horizontal stabilizers. The APU looks to be gone as well, it is aft of the pressure bulkhead.
This plane suffered a damaging tail strike several years ago. Failure years later from repaired tail strike damage brought down JAL flt 123 in 1985. And China Airlines Flight 611 in 2002. Both broke apart at altitude with no warning.
There have been other aircraft losses due to destructive decompression.
Here is one of the last pics of the plane so you can identify the parts shown in the crash photos:

Forgot to mention, it was the rear pressure bulkhead that failed first on the 2 examples I mentioned.
I sure hope this was accidental and not a case of mass murder. The world has way too much of that.
