Nicole Emmerichs was walking with her daughter Gwen Decambra in the park on Monday night when they discovered someone stole her purse and two backpacks from the trunk of her vehicle.
The pair drove around the immediate area and recovered nearly all the stolen items that night.

But they couldn't find Gwen's beloved teddy bear named "Bear."
"My dad won it for me from a Denny's," Gwen said. "But what's important is that it's been with me through a lot of stuff. My parents divorce, all my hospital stuff."
The bear was the girl's prized companion during her recent hospital stays with bouts of severe asthma.
