I might actually give Hamster some credit if he didn't go with the ninja story being the real thing. Not one shred of evidence that anyone else was involved. She admitted that it was a lie, and all evidence points to her. Which is why she changed her story to self defense. Anyone who believes the ninja story is either

or
Here is my line of thought. She doesn't remember how it all it happened. She's a photographer. If she took the gun and knife, she would be smart enough to know that simply deleting photos doesn't erase them. Washing an SD card more than likely does not damage it. The camera was found on top of the washer load. Heavy camera, would sink to the bottom. How did it move? There were bloody clothes in BOTH the washer and dryer. I don't think either side has stated how long she stayed to try and clean up. Assuming his house was built in the early 2000's, the washer and dryer were installed along with the build, so he likely doesn't have the super efficient machines. That first load in the washer took at least an hour, maybe a little longer.
One of his roommates was off work that day, and has stated he was in and out of the house many times all day. Same roommates stated he saw Travis alive after the day of the murder, as well as doing laundry after the death occurred He changed this story back and forth more than once. Then he changed his story once he heard when Travis died. Travis' dog, who fed it? It had to have been going frantic the whole time. All of his friends immediately pointed their finger at Jodi, and their stories are almost word for word the same, that's fishy to me. It took five days to report it to police. There was cleaning product left out, and somebody stated a sport looked and felt like it had been cleaned recently (a railing I believe) The roommates walked by the washer and dryer into the garage. They didn't notice any blood spots?
If he was truly messing around with 11 different women, some of them surely thought it was more than just sex. It's also likely at least a few of them were married. Husbands get suspicious. He also owned many different people money. There is motive for more than one party here I believe.
And more than anything, the sheer brutality of the murder. Historically, female murders are pretty clean overall. The extreme overkill does not equal a single females rage, to me.
