Tara Quigley says she still does not know the motive behind the attack and still suffers "horrible pain". Appearing on ITV1's Daybreak, she said of her attacker:
Some days I hate him, but the majority of the time I feel quite sorry for him, because I feel he is a child who is not capable of making an adult decision, even though he thought he did, he can't.
I was at home with my family. A young man knocked at my front door, asked me if my name was Michelle, to which I told him my name was Tara, so he left, quite abruptly. He came back about five minutes later and knocked again - as soon as I opened my front door, he just threw the acid at me.
