Still in place where? On the grate or on her neck? I don't believe any photos show the ligature around her neck. The video that shoes it dangling from the grate is after they cut her down, but they cut the ligature about halfway up, not at the top loop. So the 'noose loop' and half the length are lying next to her on the floor and the other half, including the 'anchoring loop' is still attached to the grate.
That explains it then. I’m slow. Pretty. But slow.
