Dallas police chief David Brown announced at a press conference Friday morning that one of the suspects in Thursday night’s sniper attacks that left five officers dead and seven others wounded told authorities his motivation for the shooting was that he was “upset about Black Lives Matter” and “wanted to kill white people,” especially white police officers.

“The suspect said, he was upset about Black Lives Matter. He said, he was upset about the recent police shootings. The suspect said he was upset at white people. The suspect said he wanted to kill white people, especially white officers. The suspect stated that we will eventually find the IEDs,” Brown said. “The suspect stated that he was not affiliated with any groups and he stated that he did this alone.”

“The suspect said other things that are part of this investigation, so that we can make sure that everyone associated with this tragedy is brought to justice.”

The suspect in question was killed by a police robot that carried in a small bomb after a prolonged standoff. Brown confirmed that three other suspects are in police custody.

At least two shooters opened fire on police officers at an anti-police protester in downtown Dallas Thursday night, killing five officers and wounding seven others. The shooters used high-powered rifles to target police officers from elevated positions and reportedly were wearing body armor.

Protesters gathered in Dallas after recent police-involved shootings of black men in Minnesota and Louisiana. KDFW reported that some protesters were chanting “Fuck the police” and “Black Lives Matter” prior to the shooting. It’s unclear if the shooters participated in the protests.

One shooting, which took place in Louisiana, was captured on video and is under investigation by the Department of Justice. The aftermath of the second shooting, which took place in Minnesota, was broadcasted on Facebook Live by the deceased’s girlfriend.
