I think that when the Yreka cops nabbed Jodi at grandma's home with the rental car packed with her "kill kit" (i.e., box of books secreting a couple of knives, and her brand new 9 mm handgun taped inside by the engine), that they may have stopped a potential serial killer after her first trophy kill.
She had invited herself on the camping trip with four guys she hardly knew. They were going to be her next victims out in the secluded wilderness.
I think she had learned a lot after slaughtering Travis. She had stimulated all of her senses with the killing. I'm sure she was covered in blood and felt its warmth, tasted the inevitable blood spatter on her face, heard the sounds of a dying man, saw the horrific sights, and reveled in the smell of fear and death.
Sure, her first attempt was sloppy. But she had time to process the experience and to perfect her future plans.
She thought she was never going to be caught after she had disappeared.
But those darn friendly cops who stopped by grandma's and asked to talk with her while her guard was down ... really put a crimp in her brilliant plans for her new future.
It was on "48 Hours" that she infamously stated that "no jury will ever convict me, and you can mark my words on that!". How deliciously ironic it would be if, after exactly 48 hours of deliberation*, the jury reached their unanimous verdict and convicts her.
* (of course, they'd have to stretch out that 48 hours with some card games and maybe a game of charades) :seeya:
