HOUSTON --We have an update on a young Crosby boy attacked by two pit bulls. The boy's mother says her son is showing some improvement. Mario Lopez, 10, was seriously injured when the two dogs attacked him two weeks ago as he rode his bicycle through the neighborhood. The pit bulls bit him all over his body. His mother says with some help, Mario can now walk around a little and is able to spend time outside. We're told on Monday Harris County Animal Control euthanized the pit bulls. Their owners are facing criminal charges.
