New details emerge from inside Dallas Suspects home

(DAllas , TX) –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.

Officials said this afternoon it appears that Johnson was the lone shooter. Dallas Mayor Mike Rawlings described the gunman as a “mobile shooter” who wrote manifestos on how to shoot and move.

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. His former employer, Jeppi Carnegie, CFO of Touch of Kindness LLC, said Johnson had worked for the residential health care company since January 2015. He worked from his mother’s home in Mesquite and cared for his 21-year-old brother, Carnegie told ABC News.

Carnegie described Johnson as a “good employee” and a “family man” who loved his younger brother. The company never had any issues with Johnson and was always volunteering to work more hours.
