"Kelly Martin, an alcoholic,"
I'd assume she was pizzed out of her head and so not able to judge & control her actions. I'd doubt UCs are the cause. Alcoholics find the money regardless. She needs drying out and given a desire to stay off the wagon.
Just-Jude - If you read your own link, you will see that this woman is an alcoholic with mental health problems, logic suggests you look there as the root cause of her behaviour, rather then the benefits system.
