"So very sorry": Alexis' mother apologized Wednesday to the families of the victims, saying she didn't know "why he did what he did, and I'll never be able to ask him why." "Aaron is now in a place where he can no longer do harm to anyone, and for that I am glad," she said. "To the families of the victims, I am so, so very sorry that this has happened. My heart is broken."
Thorough review: On Wednesday night, the Navy secretary ordered three reviews:
1) To see if Alexis' behavior on and off duty made him fit for duty or to hold security clearance.
2) To see if a contractor is required to inform the Navy if it reviews an employee's clearance.
3) A thorough look at how security clearances are granted and renewed in the Navy.
"Where there are gaps, we will close them. Where there are inadequacies, we will address them. And where there are failures, we will correct them," said Defense Secretary Hagel.
