A gun introduced during the childhood of local resident Keith Johnson went off near the end of his life's third act Wednesday, finally resolving the dramatic tension that had gripped the residents of Cheyenne. The revolver, which was inherited from Johnson's emotionally distant father, was a frequent background detail in the unfolding narrative, though its importance had been dismissed until a drunken Johnson brought it out in front of his wife, Susan, and daughter, Katie toward the end of his marriage's second act. While only fleeting and disconnected images were available at press time, including the gun itself smoking on the floor next to Katie's favorite doll, consequences of Johnson's action will not be known until police reopen the scene and either begin the fourth act of Johnson's life or announce an epilogue.
