In November, the judge overseeing the bankruptcy case, Dennis Montali, made it Kasolas’ job to locate victims and help them file claims. He and his staff have mailed tens of thousands of flyers that have included information in English and Spanish. They have published advertisements in newspapers and on radio and television, and posted notices on Facebook and Instagram. They have opened a call center to provide information and assist with claims. And they have created a website for people filing on their own.
