Fox News correspondent Jennifer Griffin reported the latest details on the military service record of the man who attacked Dallas police officers last night.

Micah Xavier Johnson, 25, enlisted in the Army Reserve in 2009 as a carpenter/masonry expert, deploying to Afghanistan in Nov. 2013 until July 2014.

He was honorably discharged in 2015.

Griffin said there was nothing unusual in his record and there were no "red flags."

She reported that he was not trained by the Army as a sniper and deployed with an engineering brigade, based in Seagoville, Texas.

A man who served with Johnson told Fox News that when he returned from Afghanistan, "he got in touch with some bad folks and went all Black Panther."

Johnson, a resident of the Dallas area, had no criminal history or ties to terror groups, officials said. 

He was killed in a standoff with police when officers sent in a bomb robot to detonate an explosive device. The Dallas police chief described the statements made by Johnson during negotiations.

"He said he was upset about Black Lives Matter", said police chief David Brown, adding that Johnson said he wanted to kill white people and police officers.
