It was for his young son that this New York documentary-maker decided to invest his savings with Bernard Madoff.
SOT George Nierenberg
I have a special needs child, a five year old boy. And a very close friend of our family who knew Madoff asked him if he would open an account for us. And he agreed. It was a small account, but it was meaningful to my family, especially because of my son and his needs.
George Nierenberg had believed the returns would guarantee his son's future.
But by the end of 2008, his savings had disappeared.
His parents were also caught up in Madoff's investment fraud -- losing their home and their retirement savings.
The discovery of the scam sent shockwaves around the world.
Among Madoff's overseas victims, the Spanish bank Santander and French investment bank Natixis...as well as individual investors.
In France, it's believed they've lost about 500 million euros.

There are some clients who are very wealthy. But there are also mum-and-dad investors who have been particularly hard-hit by the Madoff affair, especially with life insurance policies.
In the hope of recovering their savings, some have decided to take action against their banks.
Others in the United States are suing the financial regulator for negligence.
Even if Madoff is sentenced to life in prison Monday --
it probably won't be enough to calm the rage of investors.
