Investigators are searching the home and questioning the wife of the soldier who went on the deadly shooting rampage at Fort Hood.
Fort Hood spokesman Chris Haug says the shooter lived with his wife and children locally after transferring from another military installation in Texas in February.
The shooter, identified as Ivan Lopez by Texas Rep. Michael McCaul, killed three and injured 16 on Wednesday before turning his privately owned .45-caliber handgun on himself.
Haug said more details may be released later in the afternoon.
A hospital physician says he doesn't expect any more fatalities resulting from the shooting at Fort Hood that left three dead and wounded 16 others.
Dr. Matthew Davis said during a news conference Thursday he's optimistic none of the three critically wounded patients being treated at Scott & White Memorial Hospital will succumb to their injuries.
Davis also says "several" of the victims at the hospital northeast of Austin will be discharged Thursday. He did not say how many will be discharged. He described them as in "good spirits."
A hospital spokesman says three victims from Wednesday's shooting at the Army base remain in critical condition, two are fair and four listed in good condition.
The other victims are being treated elsewhere and the extent of their injuries is unclear.
