Report: Siblings sue Big Brothers Big Sisters, say volunteer abused them

A trio of siblings said in a civil lawsuit filed Wednesday they were sexually abused by a Big Brothers Big Sisters volunteer in the 1990s, the Chicago Tribune is reporting.

The suit alleges supervisors knew a volunteer of the program was sharing a bed with one of the boys during weekly sleepovers but failed to remove him from the mentoring program, the Tribune reports on its website.

The unnamed victims said the abuse started in 1990 and soon involved the other two brothers, the Tribune reports.

The civil filing names Big Brothers Big Sisters of Metropolitan Chicago and Metropolitan Family Services DuPage as defendants, the Tribune reports.

The plaintiffs today range in age from 29 to 33, the Tribune reports.

The alleged abuser's name is listed in the lawsuit, though not as a defendant. He is not registered as a sex offender in Illinois or the state he appears to currently resides in.
