The parents of Dallas shooter Micah Johnson say they are surprised by his violent rampage and note he returned from an Army deployment to Afghanistan a changed man.

The man who fatally shot five police officers in Dallas may have had plans for a wider attack, the city's police chief said Sunday. Dallas Police Chief David Brown provided new details about the tense two-hour standoff that police had with the gunman before he was killed.

"We're convinced that this suspect had other plans," Brown told CNN, adding that the shooter "thought that what he was doing was righteous and believed that he was going to target law enforcement and make us pay for what he sees as law enforcement's efforts to punish people of color."
