The ongoing investigation of a Madison a sexual assault and child pornography case has uncovered about 300,000 images.
Madison Police arrested Spiess, of Sun Prairie, for alleged drunk driving on Oct. 29. During the police's search of Spiess' vehicle evidence was found, which began a child sexual assault and child pornography investigation, police said. This evidence included prescription cough medicine, printed child pornography and a duffel bag containing children's underwear. There was also a cigar box containing several flash drives.
On Tuesday Spiess was re-charged with seven counts of possession of child pornography among other charges.
Authorities have been examining suspect Michael Spiess' digital storage devices found in his van, but have not began to examine his computer.
Some of these images allegedly include the suspect in sexually suggestive poses with the victims.
Assistant Dane County District Attorney Brian Asmus told the Wisconsin State Journal there is a possibility federal prosecutors might take on the case due to the volume and type of material found.
He was then re-arrested Thursday after authorities allegedly found images showing someone who appeared to be Spiess with nude boys.
No victims have been identified at this time, police said.
