Also on top of leaving the children Alive... They made sure to lock the door back. I just went back and listened to both 911 calls. I listened for keywords.. In the first 911 call the caller specifically states: 1.the door was locked 2. She knew where the key was and let herself in. This lets us know that the killer(s) were particular in locking the door back. As well as moving the bodies to the back room. If the caller obtained the key easily than it was in its normal spot. What if the killer used it to unlock the door,lock the door, then placed it back. Thinking they were doing everything right... Why would Cartel give a ....about if they locked the door back or spared the children?
The second 911 call is very compelling. He states that KR has a "gun shot wound" he says this more than once on the call and specifically only mentions a single gun shot wound. He never says multiple or wounds , just one. This makes me think maybe the killer(s) used KR to try and make it look as though the single gun shot wound was due to a suicide... To possibly hope that it would implicate KR for the entire thing... Coincidentally... The caller soley decided to check on KR but for what reason? Why him? Coincidence? Or a purpose?
