Shooting investigation ends; Giffords speaking more and more

Posted: Updated:

TUCSON, Ariz. -- All evidence in the northwest side shooting spree that killed 6 people and hurt 13 others, is in the hands of the U.S. Attorney's Office.

The FBI and Pima County sheriff's department have finished their investigations. Investigators interviewed dozens of witnesses and people who know 22-year-old Jared Loughner, the man charged in the case.

He's charged with trying to assassinate Congresswoman Gabrielle Giffords and kill two of her staffers. But more serious charges are yet to come for the 6 deaths.

And Wednesday, just over a month since the shooting, we learned the congresswoman can once again speak.

It was just another morning at TIRR memorial in Houston.

"She was having oatmeal and yogurt for breakfast."

When all of a sudden.

"She asked me for toast."

"Toast."  It was a simple five letter word that Congresswoman Gabby Giffords said to her chief of staff Pia Carusone on Monday.

"She sounded great, very clear to understand.  And I said absolutely. We asked the nurse to call the cafeteria and get some toast," said Carusone.

Early reports suggested this was the first time Giffords had spoken since last month's tragic shooting, but her chief of staff dispelled that myth.

"First time id seen her express a preference for the food and you know its hospital food so maybe she got sick of it," said Carusone.

Wednesday we learned Giffords had spoken before. What she said will be up to husband Mark Kelly to share when the time is right. Giffords' staffers credit intense therapy for their boss' speedy progress.

"She's doing speech therapy every day and she's really getting better everyday," said Carusone.

Take a look inside Giffords hospital room.

"She's happy she smiles when you walk in the room," said Carusone.

At TIRR, she's undergoing several hours of physical and speech therapy everyday. And all that work is starting to pay off.

"When I go back to Houston on Friday she'll look and sound better than she did three days ago," said Carusone.

She may even want some more toast.

Carusone says Giffords recovery is moving along quicker than most expected, but doctors say it's still too early to tell what the long lasting effects of the congresswoman's injury might be.
