A Baraboo man whose apartment was raided by state investigators last May is now facing a slew of charges related to the possession of child pornography.

The Sauk County District Attorney’s Office on Friday filed 40 felony counts of possession of child pornography against 53-year-old John L. Lomax. The charge carries a possible sentence of 25 years in prison and $100,000 in fines.

The criminal complaint says a computer forensics analyst with the Wisconsin Department of Justice examined a computer and external hard drive taken from Lomax’s apartment and identified 315 illegal images.

A document filed in Sauk County Circuit Court describes the images, many of which included prepubescent girls engaged in sexual acts.

Special agents with the Department of Justice’s Division of Criminal Investigations initially searched the downstairs of a West Pine Street home on May 7. They later raided the upstairs apartment after learning that the homeowner provided wireless Internet service to his tenant: Lomax.

Authorities charged Lomax two days later with four counts of possession of child pornography. That case has not yet been resolved.

A more thorough search of Lomax’s hard drives in December revealed additional images, according to the complaint filed Friday.

Court documents show Lomax was charged with second-degree sexual assault of a child in 2008. But that case was dismissed prior to trial.

In the prior child pornography case, Lomax was released on a $1,500 cash bond and ordered to have no contact with children under the age of 18. He also may not leave the state and may not own or operate electronic devices with internet access.

A warrant was issued for his arrest after the new charges were filed Friday.
