Three coyotes are dead following an attack on a two-year-old boy in the Dallas area last week. Wildlife workers are destroying the animals as part of an effort to remove aggressive coyotes from the area where the attack occurred. The toddler was seriously injured by a coyote while sitting on a porch last Tuesday. It's unclear if any of the coyotes killed is the one who attacked the child. Their remains are being tested for rabies and a new hotline is available for residents to report any sightings. The toddler's condition remains unknown.
