Christy has had legal custody of her sister, Tricia’s, two daughters since a few months after Tricia began serving a prison sentence for reckless homicide. Though Tricia, a recovering heroin addict, was released about a year ago, has a stable job, a car, and a two-bedroom apartment; Christie says she will never give up custody of the girls. She claims Tricia hasn’t yet proved she’s stable enough to have her daughters back.

Tricia claims she’s been clean and sober for three years, but accuses Christy of being an alcoholic who favors her children while neglecting and verbally abusing Tricia’s girls; allegations which Christy vehemently denies.

When questioned about her drinking habits, Christy says “I’m allowed to go out and drink.”

Watch the video above as Christy explains what happened the morning after she says she went out to celebrate St. Patrick’s Day with a friend.
