Interesting, I didn't realize that was why SPD feels the killer could be from out of town.
Assuming this is some serial killer from out of town, it seems like it would be very risky breaking in to a house with an alarm sign in the front yard. The person would either have to be stupid or extremely knowledgeable, or simply have inside knowledge about Allison's alarm. The bleach used to clean the crime scene seems to indicate this person was not stupid, but instead they were very careful. To me that rules out some obsessed lunatic, and points to someone who has done this before (as your quote suggests).
This person did not call or email ahead. They must have shown up suddenly. They stayed and cleaned up the scene, taking their time to be thorough. Where did the bleach come from? That would indicate premeditation if they brought it. If they found the bleach at the scene, maybe it was not planned. If they left to get bleach, again, maybe not a planned murder. So if it was not planned, what happened? Who would just show up without warning? To me, only a robber, or someone who wanted to sexually assault her would show up unannounced. Maybe sexual assault was the motive to visit her, and she fought back, and it turned into a murder. Then, the killer knew they were in trouble, and tried to clean up the scene.
Or, perhaps the killer staged the scene to make it
look like someone broke into her house, surprised her and killed her, using the bleach and the robbery to attempt to throw off investigators. IMO, whoever did this was either the luckiest criminal ever, or there is much more to this murder than the public knows.
- It has not been released that there was any indication that her alarm system was set or that she left a door/window open or accessible. Her alarm system should have recorded each "event" (regardless of if it was armed), which is how they know that a door was left open when the perp left at 1am. Her alarm did not go off. Somehow, someone got into her house and no one knows whether that person broke in, was let in by Allison, came in through a door/window that was deliberately left unlocked by someone else earlier, or was already there.
- The accidentally-released police report that was quickly removed from online stated that she put up a fierce struggle, there was evidence of head trauma and her head was wrapped in a cloth (I'm paraphrasing and can't link to the source since it's no longer accessible). Maybe an intruder surprised her and she fought him. Maybe someone was there in the house already, she got into an argument with him and it escalated to the point where he killed her.
- The substance around her body that was used as an attempt to clean up was identified as white, with a bleach-like odor. An intruder who intentionally went to sexually assault her is not going to tote along a bottle of bleach to clean up after himself. Also, to my knowledge, they have not acknowledged that she actually was sexually assaulted. I
believe that's an assumption that's been made because she was found with no clothes on. However, that could be easily explained if she'd just gotten out of the shower.
- An intruder who stuck around long enough to find a bottle of bleach would have had to be pretty confident that spending an extra however-long looking for something to clean up with wasn't going to get him caught - and if the murder was unintentional, the perp would be panicked and wanting to get out of there as soon as possible. However, someone already in the house may have known exactly where Allison kept the bleach, and he would have known he was in no danger of being caught cleaning up by someone else because he'd know that no one else was going to drop by unexpectedly.
- The robbery attempt was pathetic and I believe it was another attempt to throw investigators off. If an intruder intended to rob her, he would have bailed as soon as he realized someone was in the house, and he would have been taking a huge risk to break into a house that had an obvious alarm company sign in front. If her alarm had gone off, the police would have been notified almost immediately. However, if someone was already in the house, making it look like a robbery-gone-bad would be a logical cover.
- LE has not officially cleared anyone or declared a suspect or even a person of interest. They've stated they have the perp's DNA but it does not match any known samples in their database. They may have the perp's DNA because it was throughout the house from earlier visits, and matched whatever they may have found on her body.
As someone upthread stated, Allison was friendly, but not stupid. If she let someone into her house, especially at night, I believe she knew him well. Or he knew her well enough to have unrestricted access to her house to be able to come in on his own.
All JMO and as always, I could be completely wrong about everything.
