Rusty Ross, general manager of the Blue Star Motel in Douglas, said the cookies were made for a "best cookie" competition among 18 local motels, but the Blue Star's first foray into competitive cookies was canceled when three women pulled off a heist, WZZM-TV, Grand Rapids, reported Tuesday.

Ross said the other two women made off with the cookies while he was showing the room. He said the woman who asked to see the room left without booking a reservation or even giving her name. "If it was kids, maybe you'd say it was funny because the kids took it, but these were well-dressed grandmas, older-looking women," he said. Police are investigating and Ross said the motel is offering a free stay to anyone who offers information leading to the suspects.
