A former University of South Florida football player who was a witness in the murder trial of a white Dallas police officer has been killed in a shooting, the Dallas Morning News reported, citing authorities.

President Obama and former President George W. Bush spoke at an interfaith memorial service Tuesday afternoon for the five police officers murdered in Dallas last week.

Bush, a resident of Dallas, noted that he interacts with law enforcement every day.

"We're proud of the men we mourn," he said.

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."
