The Linnik Murder - how many illegal aliens in national sex registry?

Zine Linnik, a 12 year old girl was murdered by an illegal immigrant who was charged in 1990 with sexual incest with a 16 year old girl and that was the red flag for deportation. But that didnt' happen.

Somebody should introduce a legislative act something like the Linnik Act at the Capitol (or even at the state capitals) to help address this sort of thing as a remembrance to Zina Linnik. Didn't Adam Walsh do something like that when his boy was abducted and then murdered? What's more didn't somebody, somewhere, broke the law regarding the Adam Walsh Child Protection and Safety Act of 2006 on reporting sex offenders to the national sex offender registry database when Zina Linnik was murdered?

Here's a fact to be aware of:

Recidivism rates for sex offenders often exceed those of other criminals. The Department of Justice has found that released child molesters were more likely to be rearrested for a sex crime than released non-sex offenders. Released sex offenders were four times more likely to be rearrested for a sex crime than released non-sex offenders.

Also, I am thinking out loud here. How many illegal aliens are in that registry? What are the odds on finding one in that registry seeing that many people are so indifferent about illegal aliens in our country? Would people be that stupid to put in illegal aliens who are sex offenders in the sex offender national registry database? And if so, wouldn't that bring a lot more attention to this sordid problem when background checks and screening continually fail?

Does anyone know? Anyone care to check those names in the sex offender registry and find out? Does the White House even care? Bush? Chertoff? Hello people!
