Captain Jason Gearman of the Minnehaha County Sheriff's Office says parents need to be aware of what their children are doing on line with their computers and cell phones.

"I'm no expert on electronics but I know there are parameters that can be set on cell phones. If you are paying for the cell phone, you certainly have access to it. Just be aware of what your kids are doing on social media and on the cell phone."

Gearman says there are far too many children that are sending nude pictures of themselves to others.

"Sioux Falls Police have numerous cases. We have numerous cases. School resource officers are dealing with it...educating students to the dangers. We just encourage parents to let their kids know it can be harmful to send these pictures to somebody. They can use it for whatever they want---forever!"
