After the death of lone Dallas sniper, Micah Xavier Johnson, following a stand-off with police on Thursday, authorities have discovered bomb-making material, rifles and a combat journal at his home, Nine News reports
The US ex-soldier, who shot dead five officers from an elevated position during a ‘Black Lives Matter’ protest just before 9pm on Thursday (local time), was killed by a bomb-carrying robot after hours of unsuccessful negotiations.
Police have described 25-year-old Johnson as a “loner” who was out to “kill white officers”.
“During the search of the suspect’s home, detectives found bomb-making materials, ballistic vests, rifles, ammunition, and a personal journal of combat tactics,” the Dallas Police Department said in a statement.
“The suspect said he was upset at white people. He was upset at the Black Lives Matter protest,” Dallas Police Chief David Brown said.
Initial investigations suggested there was more than one gunman, however Dallas mayor Mike Rawlings and US Homeland security secretary Jeh Johnson have since said they believed Johnson had acted alone.
Mr Rawling said Johnson had written a manifesto, which detectives found at his home.
