SAN ANTONIO – A San Antonio woman has pleaded guilty to selling her 5-year-old daughter into a child-porn operation.

In entering a plea agreement on Tuesday, Jennifer Richards, 25, admitted she exchanged her child for a two-bedroom apartment and a used car, knowing the girl would be employed in the production of sexually explicit material. The plea cancelled one count of distributing child pornography and one count of interstate transmission of information about a minor.

According to the indictment, Richards’ then-boyfriend, Sean Michael Block, 40, aided and abetted her in the sale. Block also is charged with distributing child porn. He is scheduled for trial May 26.

According to an FBI agent’s testimony in the case, Richards and Block intended to sell both the 5-year-old and Richards’ 10-month-old daughter, who eventually would be used in the production of pornography, as well. Officials have said both children were rescued before they were harmed.

The FBI agent also testified Richards and Block were planning to abduct and “carve up” a teenage runaway.

According to court documents, Block has been under investigation since 2004, but until recently there was not enough evidence to charge him with a crime.

Richards faces 20 years to life at sentencing. If convicted, Block faces a maximum sentence of 30 years to life.
