In a heart-wrenching tragedy, a 5-year-old boy who survived the devastating tornado that hit Moore, Okla., on May 20 was killed by a dog, CBS News affiliate KTHV reported Monday. The boy and his family had been staying at a friend’s house in Jessieville, Ark., since the twister ruined their home.

According to a police report, the bullmastiff attacked the child after he had been throwing a tantrum about putting on a pair of shoes Saturday afternoon. "The dog possibly attacked because he felt threatened," Deputy Scott Hinojosa told the news station.

At first the dog's owner, 50-year-old Lynn Geiling, could not separate the two and yelled for her husband to help her. By the time he arrived, the 160-pound dog was removed from the boy but the fatal damage had already been done. Arkansas’ Fox 16 reported the boy had “major lacerations” to his head and neck.

The 5-year-old, who hadn’t been identified, was rushed to the emergency room at Mercy Hospital but he was pronounced dead on arrival.

The boy and his family were staying in Jessieville with friends after their home was destroyed by the hurricane that devastated Moore, according to Garland County Animal Control. "You can't imagine, you know, what this family and friends are going through right now," Hinojosa said.

The dog involved in the attack, who initially ran off, is now dead after a friend of the family put him down, police said. It’s not clear if the owners of the dog will face charges, Fox 16 said.
