More than 200 individuals have come forward with new allegations of sexual abuse by members of the Boy Scouts of America in recent weeks as a trio of law firms seek to uncover unidentified child abusers. A few of the victims are young, still underage or in their 20s, but many have held their secrets close for decades, USA Today reports.

Advised by Tim Kosnoff, an attorney who has litigated more than a thousand cases of sexual misconduct against organizations such as the Scouts and the Mormon church, the group of attorneys said it has identified 150 alleged pedophiles never before publicly accused. The law firms began running TV and Google ads encouraging victims to sign on as clients for a potential lawsuit after a report in December that Boy Scouts of America prepared for a possible Chapter 11 bankruptcy filing. The volume already gathered could double the number of legal cases the organization already is facing, although a bankruptcy would halt existing and future litigation, the attorneys said.
