I don't believe her....all she is saying now is “drama” and the spotlight...and I believe she is quite unstable, and that not because of her sons death. Rather her “Honor” as Mother to these two is being subject to criticism....she knows she encouraged her eldest son to go deeper into Islam when he was having difficulties.....and she herself was going deeper...as said before one of the reasons the father split was how this family had changed and would not listen to reason.....
This woman is covering big-time! and it's all about her.
The following stated continues to show she's protecting herself IMO.
“During our last conversation on the morning [before the shootout], he was especially touching and tender and alarmed at the same time.
“He said he got a private phone call from [the FBI] and said that they told him he was under suspicion and should come see them.”
The last words Tamerlan told her before he hung up the phone was, “If you need me, you will find me.”
