FORT HOOD, Texas —
A family spokesman said Thursday that Lopez was upset he was granted only a 24-hour leave to attend his mother's funeral in November. That leave was then extended to two days.
Three people who were critically injured in the attack improved to fair condition Friday at Scott & White Memorial Hospital in Temple. A fourth victim was expected to be released later in the day. At the military's request, the hospital said, it would not make the wounded or their families available for media interviews.
Also Friday, Texas Gov. Rick Perry and Sen. Ted Cruz visited wounded at a military hospital. Cruz said he was inspired by a soldier who had suffered a bullet wound to his abdomen, but still shielded other soldiers and called 911.
Investigators searched Lopez's home on Thursday and questioned his wife, who declined to comment in Spanish when reached by phone by The Associated Press.
Lopez walked into a base building around 4 p.m. Wednesday and began firing a .45-caliber semi-automatic pistol. He then got into a vehicle and continued shooting before entering another building on the Army post. He eventually was confronted by military police in a parking lot, Milley said.
As he came within 20 feet of a police officer, the gunman put his hands up but then reached under his jacket and pulled out his gun. The officer drew her own weapon, and the suspect put his gun to his head and pulled the trigger a final time, Milley said.
