This seems plainly related to safety procedures: either they weren't followed, and they were able to be not followed in a way that led to death, or they had a gap in said procedures that led to "correct" actions leading to death.
The alternative is it was intentional, which while possible generally results in articles saying something like "It is unclear what happened.<paragraph break>Hotline numbers if you need to talk to someone are ..."
This isn't inherently a failing in the safety system - no system can make something safe. Lock out tag out systems are one thing, but a plane on the apron needs to start its engines. We also need people on the apron for obstructions, maneuvering, etc.
I'm not sure how you can prevent one of those people from running at the engine intake, short of tugs pushing aircraft literally on to the taxiway (much much slower), tugs with operators who are locked into the tug, mind you, until it gets to a certain proximity from the aircraft such that the engine can be shut down? Not just that aircraft but any aircraft (or else you jump out your cab, and run to the aircraft two behind you on the taxiway and get into that plane's intake area.
Safety systems are designed to make things safer, generally, not safe.
