Losing a parent is one of the most painful parts of life. No matter how old we are when they leave us, it can be a heart-wrenching experience. Our memories are all that is left of them—and happy reminders of their love turn into our most valuable treasures.

That’s how Mara Soriano feels about a very special teddy bear that she tragically lost in her recent move to a new apartment.

The Build-A-Bear plush toy didn’t cost a lot, but it contained a recording of her late mother’s voice telling her that she loved her and was proud of her. The bear, called “Mama Bear,” was in a backpack that contained electronics like an iPad and a Nintendo Switch. When the bag was stolen last week during the move, the 28-year-old, was heartbroken—not for the gadgets, but for Mama Bear.

So she posted online about the item lost in Vancouver, Canada, and the story behind it, which caught one viewer’s attention in a big way.

Diagnosed with cancer 10 years ago, Mara’s mother, Marilyn, gave her daughter the bear as a gift in 2017. As her cancer progressed, until her death last June, the gift felt even more special. “That bear was basically the last reminder of the mom that I knew—it was her voice that I remembered growing up,” she said in an interview with CTV News. 

Luckily, the internet did its thing and Mara’s search soon went viral. Meanwhile, Mara was out searching. She put up posters, dug through dumpsters, and communicated with others online, following any leads she could.

Actor Ryan Reynolds, a native of British Columbia, then posted a plea for its safe return. “I think we all need this bear to come home,” he wrote. Along with the message, he also offered a huge incentive for the thief—a $5,000 reward, “no questions asked.”
