DENVER — A dog stolen from a Bonnie Brae home on Halloween was reunited with her owners Wednesday morning.

Stella, a Yorkshire Terrier mix, was reportedly stolen by trick-or-treaters. The 5-year-old dog is small, weighing about 6 lbs.

According to her owner, a woman spotted Stella being sold by a man in a red van outside a retail store in southeast Denver. The family says the woman told them she recognized the dog from flyers and paid the man $400 for her.

She called Stella’s family just after midnight Wednesday to say she had their dog.

The dog’s family paid the woman who found the dog a $2,500 reward.

The Shermer family said 9-year-old Mason was passing out candy on his family’s porch when the tiny dog was taken.

“I had Stella out here sitting with me while we were giving candy away,” said Mason. “I looked at another person and gave them candy, and then I looked back, and she was gone.”

Mason said a group of teenagers quickly took off with the dog.

But Wednesday night the Shermer family told FOX31 and Denver police they believe the woman who returned the dog might have been involved in stealing the dog.

The family says police told them they are investigating.
