A community activist in Chicago, Illinois, has been convicted of attempting to blackmail gospel singer DeLeon Richards-sheffield and her New York Yankees baseball star husband Gary Sheffield.

Derrick Mosley told the couple he had access to a video tape featuring Richards-Sheffield engaged in a sexual act with an ex-lover, and planned to go public with the seedy recording unless they paid up.

He was convicted of extortion and wire fraud on Monday (14NOV05) for allegedly plotting to extort money from the Sheffields. Mosley will be sentenced in January (06).
