LUMINOL FOOTPRINTS

When investigators applied luminol to the crime scene, they found a set of footprints. Steve discusses the path he took that night when he got home:

Yes, those are my footprints, because they are consistent with everything I did when I got home that evening. We take our shoes off at the door, so we have sock feet in the house. 

That big blood cleanup spot that they mention is in a small hallway right in front of the bedroom. 

So I walked through that with sock feet and therefore spread it where I walked after we found Amy. I would've walked through it at least 4 times. 

To Amy the first time, back to Joe, back to Amy as requested by 911 to check her vitals, back to Joe. The number of footprints match those trips. 

Each time my socks would pick up some more of that blood residue, even though I couldn't see it. If there were no footprints, it would be incriminating because either I didn't check on Amy or I did a cleanup job prior to calling the police.

The bathroom, was Joe's bathroom where he was. The only footprints that are by the sink have the toes facing away from the sink because Joe and I were leaning against the sink and looking at the back wall. 

Then the footprints go to Joe's bedroom which is where we went to sit down. The 911 operator told us to go outside, so we passed through the laundry room to go outside. There is one set of prints, heading out the garage door and not near the sink.

When I gave my first interview to the police, the night she died, I gave details about where I walked in the house when we found Amy. This was before any luminol, and before any pictures. Then the evidence came back and matched my description ... isn't that how it's supposed to work? But rather than that being a good thing the police turn it into a negative.

Here are the oddities that they don't bring up. The 2 closest sinks are the kitchen sink and the master bathroom, both of which have towels or rags. If I was cleaning up, then wouldn't I use a close sink instead of walking all the way across the house? Amy was moved to the bedroom, so why are there no footprints around her body? The one set of footprints in the laundry room don't go near the sink or washer/dryer. Additionally if those were made during clean up, but also match my path after we found her, then there should've been footprints coming into the house when we returned as well, but there weren’t.
