A Marquette Heights man downloaded hundreds of photos and videos depicting child pornography onto a computer he sold to a pawn shop, charges filed Friday allege.

Alexander Krohn, 24, likely faces prison if he’s convicted in the nine-count case. He was released from custody Monday after posting a $1,500 cash bond.

Krohn was charged with three counts of possessing child pornography featuring children under age 13 and six more of the crime involving teenagers under 18. The former crimes carry prison terms up to seven years, the latter up to five.

Krohn told police he downloaded the images in late 2016 or early 2017 onto a hard drive after he found them on the “dark web,” a prosecutor’s court affidavit stated.

He said he put the hard drive in storage and had forgotten about its contents when he sold it to the Pawn King pawn shop in Pekin on April 24, the affidavit stated.

A pawn shop employee contacted police after he found the images while processing the hard drive for sale. Detectives, using law enforcement software, discovered hundreds of movies and photos depicting children in actual or simulated sexual activity, the affidavit stared.

Krohn, who has no prior criminal record in Tazewell County, is scheduled to next appear in court June 7.
