Fort Lauderdale police are searching for a young boy seen on surveillance video chasing and killing a duck in a resident’s yard this week, an incident investigators are treating as an animal cruelty case. The footage shows two children running toward a duck, with one child chasing it, catching it and repeatedly stomping on it until it died. Detectives have released the video seeking the public’s help in identifying the child. A $5,000 reward is being offered for information leading to an arrest.
