Gathering evidence and information, that's where the case stands tonight after investigators determined a former Navy
Reservist acted alone.
Details are still surfacing about the shooters violent past and mental issues that'll hopefully help
detectives determine a motive and maybe give survivors even victim's families a better understanding of how this happened.
"My husband just went to work" devastated "It can't be, it's one of those things that happens to other people it doesn't happen to me"
says Patricia Arnold, the mother of one of the 12 victims killed in D.C.
But all survivors and relatives of the dead are in mourning tonight and still trying to figure out how this happened.
"He was just going to work" a relative sobbed when Aaron Alexis entered building 197 at the Washington Navy Yard.
He was armed with a shot gun he'd purchased days earlier and carrying a valid i-d card.
The FBI confirmed he'd been employed as a contractor and passed security background checks.
They also learned prior to the deadly rampage he'd visited a gun range then hours later the 9-1-1 calls.
"We've got a report on the 4th floor a male with a shotgun, multiple shots fired, multiple people down. We have an active
shooter on the 4th floor I'll give you update on building location with several victims down. We have an officer down, building
197 on the third floor."
It's a tragedy felt by many across the nation and according to the suspects brother-in-law it's also being felt by his family,
"Their initial reaction I wasn't here for. But when I got here, they were very distraught, very stressed out, in tears, they didn't see it
coming. It's very hurtful. Their hearts are going out to the victims; the people who got hurt" says Anthony Little.
"We believe Aaron Alexis acted alone, as such, with no other suspects at large, investigation moved into evidence recovery and
information gathering" confirmed an FBI spokesperson who added how this part of the investigation is "crucial" into learning why
or what drove the shooter to do this something survivors want to know too,
"I'm not through it yet, and I'll never be through it I'll never. Everyday It'll never be over" says Arnold.
