AG got three years custodial sentence for this, and manslaughter carries no mandatory custodial sentence, the judge could have given her community service or a suspended sentence.
Therefore on top of what we know:
That she did step towards and admits she may have made light contact with the cyclist.
That she did intentionally, not accidentally, raise her hand to the cyclist.
She did NOT step away or attempt to avoid a collision.
She was evasive when interviewed.
She did leave the scene and didn't appear to show remorse
We can also see that her CP does not seem to severely affect her ability to walk, presumably nor does her visual impairment or she'd be using some sort of aid, she can clearly see the cyclist and does not attempt to avoid them.
There must be factors we do NOT know here, like how soon after the incident did she leave the scene? Did she make any attempt to help the victim?
She could also have been given a much longer sentence, life is possible (though rare) for manslaughter.
Not that I think the cyclists behaviour is actually relevant here, after all if she had committed a crime in cycling where she did, it still wouldn't exonerate AG - if the police can't quite work out if thats a shared use path or not, its pretty reasonable to suspect the victim did not believe herself to be breaking the law!
