The Denver shooting suspect may have offered clues in books he wrote under a pseudonym.

Lyndon James McLeod, 47, the suspected shooter in a Denver shooting spree, wrote a series of three books, Sanction, under the pseudonym Roman McClay, according to multiple outlets. In the books, the main character, Lyndon MacLeod, shot people at a tattoo parlor on 6th Avenue, two of whom shared names with victims of the actual Denver shooting.
