MADISON, Wis. -

A Juneau County man has been bound over for trial on 20 counts of possession of child pornography.

Bradley Carver, of Necedah, waived his right to a preliminary hearing Thursday in Juneau County Circuit Court.

The charges resulted from an investigation by the Wood County Sheriff's Department into the use of "peer-to-peer" file sharing programs for distribution of child pornography.

According to the criminal complaint, a Wood County investigator was able to monitor traffic on the peer-to-peer software and saw files suspected to be child pornography distributed through an Internet protocol address that was later determined to be assigned to Carver.

In addition, the criminal complaint alleges that when a search warrant was conducted of Carver's computer and digital storage devices, more than 10,000 images and videos of suspected child pornography and child erotica were recovered by investigators.

The maximum possible penalty for each count is a term of imprisonment not to exceed 25 years or a fine of not more than $100,000, or both.

An arraignment has been scheduled for Sept. 13.
