More than 2,200 images of Child Pornography found on iPods and thumb drive, some of it showing babies.

A registered sex offender from Arlington TX was sentenced to 15 years in federal prison Tuesday for possessing hundreds of images of child pornography, some of which showed babies.

Steven Lass, 33, pleaded guilty in April to one count of possession of child pornography, according to a release from the U.S. attorney’s office.

In August 2014, Lass was pulled over by a Midlothian police officer who noticed that the passenger seat of Lass’ vehicle was missing.  In its place were tools and electronic devices, including two iPods and a thumb drive later found to contain more than 2,200 images of child porn.

The evidence was seized by the FBI, whose investigation revealed “the lewd and lascivious exhibition of the genitals and public are of minors,” Assistant U.S. Attorney Camille Sparks said in a written release.

Lass was required to register as a sex offender after a 2005 arrest in Euless.  He was convicted of indecency with a child, an 8-year-old girl, sentenced to nine years and later paroled.
