It’s stories like this that remind us there’s a tremendous amount of good left in the world.

A young girl from Wisconsin suffering from an inoperable brain tumor got the surprise of her life thanks to nearly 40 different police departments from around the state.

This is 7-year-old Emma Mertens.  In January, she was diagnosed with Diffuse Intrinsic Pontine Glioma, which is a rare brain tumor.

Soon after she was diagnosed, she started asking people for photos of their dogs to cheer her up. The Wisconsin Humane Society put out a call for photos and they started flooding in.

Since January, she’s received countless letters and photos from friends and supporters all wanting to cheer her up.

But this weekend, she was blown away by some surprise visitors.

K-9 officers from nearly 40 different police departments showed up at her house in Hartland, which is about 25 miles west of Milwaukee.

“Today, just a few of us (roughly 40) stopped by to see Emma,” the Hartford Police Department wrote in a Facebook post. “She had no idea we were coming so she was VERY excited. What an amazing and strong little girl. It was such a great morning.”
