>> james and katelynn set up house together here in the foothills of the sierra nevada mountains, coincidentally, just a few miles from rachel and todd winkler's airpark. james started a handyman business and again, pure coincidence, got some jobs at the airpark. he also started a website called ammosmith.com. not so much about guns as about the craft of creating custom ammunition. >> we have an automatic pistol that shoots a rimmed revolver cartridge. >> and that was his life in the spring of 2010, a nicely varied little business. a second marriage, that was not going terribly well, oh, and he had a secret mad crush on the beautiful young woman who managed the airpark. rachell winkler. >> and then one day she called me into her office. this is in june, beginning of june of 2010. she said, "have a seat." and i said, "okay." i thought i was in trouble.
