Federal prosecutors have sent “target letters” to the children of some parents charged in Operation Varsity Blues, which blew open a college admissions scandal, TheWall Street Journal reported. The letters sent to current college students or recent graduates inform the recipients they may be targets of the continuing investigation. The Journal reported that the move could convince some parents to cop pleas in the case. Thirty-three parents have been charged with paying bribes or paying for better test scores to get their kids into top colleges. Thirteen, including actress Felicity Huffman, have agreed to plead guilty.
