Angela Martin, a Connecticut woman charged with production, distribution and possession of child porn last month, was already a registered sex offender.
Convicted in 2006 of sexually assaulting a minor, she was charged by federal authorities this time for sexually abusing a 3-year-old girl, which she recorded.
The video of the abuse on her cell phone was allegedly sent to someone in California. Federal authorities say she also received and distributed other material.
In connection with the 2006 conviction of second-degree sexual assault of a minor she served 30 months in state prison and had to register as a sex offender.
The case, eerily similar to that of Heather Koon, was investigated through a joint operation conducted by the Wallingford, Conn., P.D., the FBI and other officials.
