UVALDE, United States, May 29, 2022 (BSS/AFP) - US President Joe Biden will
visit Uvalde on Sunday to console residents mourning 19 children and two
teachers who were gunned down at an elementary school in the small Texas
town.

Harrowing accounts are emerging of the ordeal faced by survivors of the
Tuesday attack, as Biden calls for action to prevent future massacres in a
country where efforts to tighten firearms regulations have repeatedly failed.

"We cannot outlaw tragedy, I know, but we can make America safer. We can
finally do what we have to do to protect the lives of the people and of our
children," Biden said Saturday in a speech at the University of Delaware.

"So I call on all Americans this hour to join hands and make your voices
heard and work together to make this nation what it can and should be," the
president said.

As residents gathered in a central square in Uvalde to pay homage to the
victims, haunting stories told by young students who played dead while a
gunman killed their classmates and teachers were underscored by accounts of
the slow reaction by police.

Ten-year-old Samuel Salinas was sitting in his fourth-grade classroom when
the shooter, later identified as Salvador Ramos, 18, barged in with a
chilling announcement: "You're all going to die."

Then "he just started shooting," Salinas told ABC News.

Texas authorities admitted Friday that as many as 19 police officers were in
the school hallway for nearly an hour without breaching the room where the
shooter was, thinking he had ended his killing. Officials called this delay
the "wrong decision."

Ramos was finally killed by police.

Survivors of the attack have described making desperate, whispered pleas for
help in 911 phone calls during his assault. Some played dead to avoid drawing
the shooter's attention.

Eleven-year-old Miah Cerrillo even smeared the blood of a dead friend on
herself as she feigned death.

- 'Don't move' -

Salinas said he thinks Ramos fired at him, but the bullet struck a chair,
sending shrapnel into the boy's leg. "I played dead so he wouldn't shoot me,"
he said.

Another student, Daniel, whose mother would not provide his last name, said
he saw Ramos fire through the glass in the classroom door, striking his
teacher.

The bullets were "hot," he told The Washington Post, and when another bullet
ricocheted and struck a fellow student in the nose, he said he could hear the
sickening sound it made.

Though his teacher lay on the floor bleeding, she repeatedly told the
students, "'Stay calm. Stay where you are. Don't move,'" Daniel recalled.

He was finally rescued by police who broke the windows of his classroom.
Since then, he has had recurrent nightmares.

By mid-morning Saturday, several dozen people had gathered at Uvalde's
courthouse square, which has become a somber place of homage to victims and
survivors.

Twenty-one simple white crosses have been erected around a fountain -- one
for each victim.

People have left growing piles of stuffed animals and flowers, as well as
heart-rending messages: "Love you" and "You will be missed."

Local resident Humberto Renovato, 33, asked those present to hold hands, form
a circle around the crosses, and pray.

He also urged those gathered at the courthouse square to help survivors
overcome "the trauma, the pain, the suffering" they had endured.

Vice President Kamala Harris on Saturday attended the funeral of a victim of
another recent mass shooting -- Ruth Whitfield, who was among 10 people
killed when a self-described white supremacist opened fire in a supermarket
in Buffalo, New York on May 14.

"We will not let those people who are motivated by hate to separate us or
make us feel fear," Harris said at the funeral for the 86-year-old.

- 'Have the courage' -

She also urged US lawmakers to take action on guns.

"Congress must have the courage to stand up, once and for all, to the gun
lobby and pass reasonable gun safety laws," Harris tweeted.

The Uvalde shooting was the deadliest school attack since 20 children and six
staff were killed at Sandy Hook Elementary School in Newtown, Connecticut in
2012.

Steven McCraw, director of the Texas Department of Public Safety, revealed on
Friday a series of emergency calls -- including by a child begging for police
help -- that were made from two adjoining classrooms where the gunman was
barricaded.

But, explaining the delayed reaction by law enforcement, he said the on-scene
commander believed at the time that Ramos was in there with no survivors
after his initial assault.

McCraw separately told reporters, however, that a 911 call from a child
received at 12:16 pm reported eight or nine children still alive.

As many as 19 officers were outside the classroom door at that time,
according to McCraw's timeline.

McCraw said the child, who dialed 911 multiple times -- begged for police to
come. Her final call was cut off as she made it outside.

Back at the courthouse, Bear Berman walked around with his Golden Retriever
named Macy, letting children and adults approach and pet her.

"Dogs have a natural ability to lower blood pressure and cause the body to
release oxytocin, which is a calming hormone," said Berman, who traveled to
Texas from Florida and is part of a group that brings emotional support dogs
to the scenes of tragedies in the United States.

"So the dogs will bring that out and they'll listen to what's heavy on your
heart, they won't tell your secrets, they'll just bring happiness."
