In the past four years the Indiana Crimes Against Children Task Force has investigated nearly 3,000 cases related to child pornography.
Officials tell 14 News the tips they receive are coming from an unsuspecting source.
Those 3,000 investigations were a result of more then 4,000 cyber tips.
Some came from the National Center for Missing and Exploited Children. Others came from Internet Services Providers, and now some from repair shops, who tell us they never thought backing up a laptop would reveal such dark secrets.
Gary Barr is a 30 year veteran in the computer repair business.
Most frequently, customers have problems with viruses and backing up their devices.
Barr says while they are working in the folders, files are often in preview mode and reveal images and videos. He says in some cases, the images are left right on the desktop.
In those cases, he knows exactly what to do.
"If an image comes across that reminds you of your own kids or someone in your family or your next door neighbor, it affects you immediately and it makes you angry that you witness something like that," said Barr." "So turning it over to the police department is an easy job to do after that."
14 News also say down with an Indiana State Police Investigator.
He told us the number of investigations this year is rising and it could be related to a new, very disturbing trend he's seeing.
