As the US reels from two mass shootings, more details are starting to emerge about the victims of the attacks.
Thirty-one people were killed in a period of less than 13 hours over the weekend. The first shooting at a Walmart in El Paso, Texas killed 22. Nine more died in an attack on a busy nightlife district in Dayton, Ohio.
Here is what we know about the victims.
The victims of El Paso, Texas
The 15-year-old's friends say he could make anyone's day better with his positive energy.
Confirming his death, his aunt, Elvira, posted on Facebook that "many tears were being shed" for the teenager.
His friend Alexis Acosta, told mourners at a vigil: "If my friend was here, he would tell us everything is going to be OK.
"He would say to live on. Don't let the pain take over."
Javier's teacher, Adrian Barros, told the vigil that "with a small simple smile or a flick of his hair he would light up the room" and that he usually would enter the classroom with a football at his feet.
"I would try to kick it away from him. But he was too quick with his feet," he said.
Javier hoped to be a professional athlete and is thought to be the youngest victim of the El Paso shooting.
"As an athlete he was a fierce competitor on the field but most importantly he was the ultimate team mate," said Mr Barros.
His parents watched from the front row as respects were paid to their fallen son, with Javier's sister, Joanna, trying in vain to comfort their mother. The three members of the Rodriguez family took to the stage as 22 doves were released into the air - one for each victim of the mass shooting.
Jordan and Andre Anchondo
The young couple had just celebrated their first wedding anniversary and were shopping for back-to-school supplies when they were targeted by the attacker.
They gave their lives to save their two-month-old son, relatives said.
Doctors said the little boy's broken bones suggested his mother Jordan, who was 24, had tried to shield him from the onslaught, falling on him as she was shot; family members said that Andre, 23, tried to shield the mother-of-three as he was fatally injured.
"I forgive him because he was not in his senses. He had the devil inside of him. I'm a great believer and I forgive what he did," Gilbert Anchondo said.
The 86-year-old last spoke to her son at 10:30 local time on Saturday morning, while she was in the check-out queue at Walmart.
Minutes later, the gunman entered.
Her distraught daughter was later filmed at the scene, begging for information about her mother.
Her family confirmed to CNN she had died on Sunday.
Leo Campos and Maribel Hernandez
Family confirmed to CBS4 that the couple had died in the shooting on Saturday.
According to the broadcaster, the family first knew something was wrong when the dog groomer called to say they had not picked their pet up.

He had been out with his wife, who managed to escape.
