I think she stepped on a landmine.
Paul McCartney’s wife (2002-2008) Heather Mills lost her leg to amputation after a police motorcycle damaged it in a chase. She learned that many children step on landmines in former war zones and lose their feet or legs.
She and McCartney raised money for landmine removal projects. Adopt a Minefield charity beginning in 2000s. Sadly, similar to Minneapolis, there have been allegations that some of the millions went to offices of that charity that “ceased to exist” according to court records.
There is still an Office of Weapons Removal and Abatement at the State Department.
Can’t rule it out based on the lack of info in this “story”.
