It was her father that made the investment, not her. From the article:
“It was less than $400,000 - not a large amount by Madoff standards - but his friend helped him get into a fund. Dad was sure that he had made a wise investment and that he and his wife could be comfortable for the rest of their lives.”
That doesn't really make it clear who's money it was, it just says who invested it. Her father could have directed her money.
Not really important anyway as some one lost the 400K
