I was following this pretty closely before I headed out of the country on vacation...
Simmons was on the Ron and Don show a few days ago and there were some things from that interview that I haven't seen posted on here. You can listen to the interview here, they were nice enough to post it as a standalone clip:

The big thing that I haven't seen posted on this site, is that, based on that interview and the other stuff I have read, I _think_ that Shantina's mom was the only witness to her ex's abuse of Azriel. I am not sure that the seriousness of it was outlined here, I think his arm was broken and he was choked and he ended up in the hospital. Anyway, sometime after that happened, the grandmother committed suicide, and since she was the only witness, the charges were dropped. Thinking about it later, that doesn't make a ton of sense, Shantina must have chosen not to pursue charges, but that's pretty common in abusive relationships.
I don't necessarily think Simmons has anything to do with her disappearance, but I don't know that I buy his story. Googling your health problem and seeing that it is potentially serious is concerning, but who takes that so seriously that they supposedly have their first drink in two years? And that doesn't match up with the Facebook photo of her having a beer with pizza.
My guess is that she is an alcoholic, and has been having problems for awhile, and he has been trying to hide it for some reason. Maybe he felt like if people thought she was drunk they wouldn't look so hard?
I am sure 97.3 KIRO fm will be covering this off and on all day on their talk shows. You can listen live at

My hunch is that there is foul play involving Azriel, probably by his mom. Maybe she was suicidal. Simmons said she recently got in touch with an ex to tell him she forgave him. She also got in touch with step-relatives for the first time in years. Azriel was out of touch with his biological dad for years, and it sounds like they were only relatively recently put back in touch. Maybe she was trying to say goodbye.
Oh! The other thing I have heard is speculation that her lightning bolt tattoos on her back are a white power symbol. Which seems completely unrelated to anything, but since people on this site like to analyze every detail, I thought I would throw it out there.
