Authorities say they found bomb-making materials while searching the home of the man who shot at Dallas police Thursday night.

Investigators also found ballistic vests, rifles, ammunition and a journal of combat tactics at Micah Johnson's home.

Detectives are working to analyze the information in the journal. Johnson was an Army veteran who police say was described as a loner.

Johnson was killed in a standoff with police after he killed five cops and hurt seven others. (Metro Networks Inc.)
