(CNN)Claudia Patricia Gomez Gonzalez traveled 1,500 miles to the United States, hoping to find a job and a better future. Shortly after she set foot in Texas, a Border Patrol agent shot and killed her.
She came to the US for a better life. Shortly after her arrival, she was killed
Gomez Gonzalez's shooting Wednesday drew international attention after a bystander posted video of the aftermath on Facebook Live, showing her lying on the ground, bleeding.
Authorities changed their initial account of the shooting two days later, adding to the controversy at a time when the White House has cracked down on undocumented immigrants.
The deadly encounter ended the journey Gomez Gonzalez started nearly three weeks ago in an indigenous community in San Juan Ostuncalco, Guatemala.
Gomez Gonzalez earned a degree in accounting two years ago but had not been able to find a job.
"She looked, looked and nothing," said her father, Gilberto Gomez. "I believe that's the reason why she decided to pursue the 'American dream.' "
The lack of job opportunities frustrated her, and she decided to leave home and head to the United States to find work. She was following in the footsteps of her boyfriend, who made the same journey about a year earlier.
The 20-year-old had been traveling for more than two weeks with other migrants when they encountered a Border Patrol agent in a residential area of Rio Bravo, Texas, about a mile from the Mexican border and 170 miles south of San Antonio.
The agent -- a 15-year veteran -- fired one round from his service-issued firearm, fatally wounding Gomez Gonzalez, US Customs and Border Protection said. The agent, who has not been identified, remains on administrative leave.
In between sobs, the woman's mother, Lidia Gonzalez Vasquez, said she only wants her daughter's body back.
"My girl did not go there to steal; my girl left to move forward and go to school," she said.
Her family asked for justice at a news conference Friday in Guatemala.
"It's not the first time someone dies in that country (United States)," her aunt Dominga Vicente told reporters. "There are many people who have been treated like animals, and that isn't what we should do as people."
Rallies took place around the country over the weekend, including one in Los Angeles, where dozens called for justice and a transparent investigation.
Gomez Gonzalez's body will be repatriated to Guatemala by this weekend, according to Tekandi Paniagua, the head of Guatemala's Consulate in Del Rio, Texas.
"Guatemala condemns violent acts and any other use of excessive force by the Border Patrol. We urge authorities to respect the rights of our citizens, especially their right to live, regardless of their immigration status," Guatemala's Ministry of Foreign Affairs said earlier.
Two days after the shooting, Customs and Border Protection revised its account of the shooting, raising questions about what actually happened.
The agency initially reported the Border Patrol agent responded to a report of illegal activity Wednesday and was attacked by migrants armed with "blunt objects." In its latest version of events, it made no mention of any objects and only indicated the group "rushed" the officer after ignoring orders to get on the ground.
Additionally, the Border Patrol at first reported that a round from the officer's gun "fatally wounded one of the assailants," but the latest statement referred to the gunshot victim as a "member of the group."
A lot of the details on the shooting have not been made public.
Customs and Border Protection canceled a news conference on the shooting and instead released an updated statement. An agency spokesman declined to comment further, saying the shooting was under investigation by the FBI and the Texas Rangers. An FBI spokesman declined to comment, citing an ongoing investigation.
Marta Martinez, who recorded the aftermath of the shooting on her cell phone and posted videos on Facebook Live, was getting ready to attend her son's award ceremony at school when she heard a gunshot.
She ran out of her home and saw an officer turn over the body of a young woman.
The woman, Martinez said, was face-down on the ground, and her face was covered with dirt on one side and blood on the other.
"I don't think there was no reason to shoot a girl like that, not even in the head," Martinez said.
In the video, a uniformed man is seen giving someone on the ground chest compressions, but Martinez said the woman appeared to be dead.
In a vacant lot near her home, Martinez said an agent captured two men who ran from the scene after the shooting. She said she heard the officer tell the men: "This is what happens. You see?"
Agents arrested three undocumented immigrants, according to Customs and Border Protection.
In her video, Martinez can be heard yelling in Spanish at the officer who led the men to his vehicle: "Why do you mistreat them? Why did you shoot the girl? You killed her. He killed the girl. She's there. She's dead. I saw you with the gun, bro."
