Dallas police chief claims racial motive in sniper attacks: 'He wanted to kill white people'

One of the suspects in the deadly sniper attack that killed five police officers in Dallas and wounded six more said he was upset by recent police shootings of black men and wanted to kill white cops.

Dallas Police Chief David Brown said the attackers likely knew the march route and "triangulated" their targets from above, reported USA Today.

One of the gunmen was killed by a robot-delivered bomb, and three suspects were taken into custody.

The chief corrected previous reports that the suspect had shot himself.

Brown said the suspect seemed lucid during the interview, and he warned that the assailants had placed improvised explosive devices throughout the area.

Dallas Mayor Mike Rawlings said the surviving suspects were "pretty tight-lipped," and he would not rule out possible links to terrorist groups.

Investigators told CNN that they found no evidence of connections to international terrorist groups.

The police chief said the slain suspect told investigators before he died that "he was upset about Black Lives Matter (and) he wanted to kill white people, especially white officers."

The suspect said he was not affiliated with any groups but operated independently.

Three of the officers remain in critical condition, and two civilians were also wounded in the attacks.
