An Alabama woman is charged with filming a 19-year-old man performing sex acts on her 1-year-old granddaughter and streaming the videos to an online pornography service.

The Alabama State Bureau of Investigation arrested Lisa Williamson, 41, and Steven Anthony Jackson late Thursday, WTVY reported.

Williamson has been charged with permitting a child to engage in production of obscene material, sex abuse of a child, production of child pornography, dissemination of child pornography, and possession of child pornography. Jackson has been charged with production of child pornography and first degree sodomy.

WTVY said that both Williamson and Jackson, from Hartford in southeastern Alabama near the Florida state line, are being held in the Geneva County Jail.

The station said law enforcement got a tip from out of state about the pornography operation. Authorities say Williamson filmed Jackson performing sex acts on the child, including oral sex, and may have been using a subscription service online for distribution.
