(DALLAS) — The suspected gunman in an attack on police officers in Dallas -- which left five cops dead and seven injured -- had bomb-making materials, ballistic vests and rifles in his house, police said.
The news from police came as police pieced together the background on the suspect, 25-year-old Micah Xavier Johnson, in the ambush-style shooting Thursday night.
Detectives are also analyzing information in a "personal journal of combat tactics" they recovered, Dallas police said.
Johnson, who was killed by police when they detonated a bomb delivered by robot, served as a U.S. Army reservist until April 2015. He was trained and served in the Army Reserve as a carpentry and masonry specialist, defense officials said.
Johnson, a private first class, was deployed to Afghanistan from November 2013 to July 2014, according to his service record.
Police said Johnson had no criminal history. Police said "others have identified him as a loner."
Police said in a statement that Johnson's Facebook account: "included the following names and information: Fahed Hassen, Richard GRIFFIN aka Professor Griff, GRIFFIN embraces a radical form of Afrocentrism, and GRIFFIN wrote a book A Warriors Tapestry."
Further details were not immediately available.
During the overnight standoff that led to his death, the suspect told a hostage negotiator that he was upset about the recent police shootings of two black men and that he wanted to kill white people, especially police officers, Dallas Police Chief David Brown said at a news conference this morning.
The suspect "wanted to kill officers" and "expressed anger for Black Lives Matter," Brown said.
"None of that makes sense," Brown said.
The suspect also said he was not affiliated with any groups and that he was acting alone, Brown said.
After officials negotiated with the suspect for several hours overnight and exchanged gunfire with him, Brown said, police "saw no other option but to use our bomb robot ... for it to detonate where the suspect was."
Dallas Mayor Mike Rawlings said this morning that because of the ongoing investigation, no information will be released right now about three other suspects in the shooting who have been arrested.
Brown said this afternoon, "through our investigation of some of the suspects, it’s revealed to us that this was a well-planned, well thought out, evil tragedy by these suspects. And we won’t rest until we bring everyone to justice."
