A Des Moines man is charged with 10 counts of child porn possession after spilling gravy on his laptop and taking the computer to Best Buy in attempt to save his files, court documents said.

Robert Leo Watson, 54, allegedly took the computer to the repair desk and purchased a new computer for his old files to be copied to. As the Geek Squad employees transferred his documents from the "gravy covered computer" to the new device, they spotted what they thought was child porn, a criminal complaint said.

Des Moines police collected both computers as evidence, according to the complaint, filed in late April. Watson was arrested and booked Wednesday morning.

As a first offense, the child porn possession charges are an aggravated misdemeanor.

Police said Watson was able to describe several images detectives found. He admitted to saving the images with file names such as "13 year old" and "14 year old's" (sic), documents said.

Watson remains at the Polk County Jail with a $50,000 cash bond. He is expected in court on May 10.

Documents show he applied for court-appointed counsel Wednesday. It was not clear if his request was granted.
