""All the time he was a problem,” said Dr. David Lazala, who trained Bello as a family medicine doctor. When Bello was forced out in 2015, he sent Lazala an email blaming him for the dismissal."

If Dr. David Lazala is of Mexican decent then we can safely assume Dr Bello, a black Nigerian, was a target of Mexican hate crime against blacks so Bello got even. Tons of public crime data supports  the countless hatred, discrimination, violence and homicide rates against blacks by Mexicans. I wouldn't be the slightest bit surprised if Bello was falsely ousted with unproven allegations to make him go ape $hit crazy and kill others and eventually himself.
