Dallas Police Chief David Brown has unexpectedly announced that he is stepping down from his position.
Brown became a national figure after leading his city and the rest of the country in remembering five officers shot and killed in a July shooting rampage.
He announced Thursday that he would be retiring from his department after 33 years on the force, the last six as police chief.
Brown, 55, did not give any reason for his departure, though said that he would leave his position in October after a “difficult decision.”
The chief’s statement also referenced those who were killed by gunman Micah Johnson on July 7 on the sidelines of a march against police brutality.
“Their memory will remain with all of us forever. I know the people of Dallas will never forget the ultimate sacrifice they made on the streets of our city that awful night,” he said.
Brown, who said he joined the police in the 1980s because of crack cocaine’s effect on the neighborhood where he grew up, had won praise before Johnson’s shooting for reforming and trying to improve the relationship between his officers and the communities they serve.
He had himself suffered the effects of violence, when his mentally ill son David Brown Jr. was shot dead by police after killing a cop and a bystander.
Some had speculated that Brown would resign after the loss occurred just weeks into his term as chief, though he would continue and implement policies promoting community policing and stricter use of force rules.
However, some police in Dallas were “frustrated” by changes to schedules sending more officers into evening shifts and a task force on violent crime, according to KXAS.
The Black Police Association of Greater Dallas sent a letter to the mayor in March saying that it no longer supports the chief.
Brown said Tuesday that he will hold a press conference next week to discuss his decision to retire.
