MEXICO CITY — Jefferson's face was covered in fake blood as he talked about leaving El Salvador for the United States after gangs beat him up for wearing women's clothes.

The 17-year-old was wearing a cadaver costume to go trick-or-treating with a group of teenagers on the south side of Mexico City, where U.S.-style Halloween mixes with Mexico's Día de los Muertos. He had also helped build an altar of offerings of food and flowers for the dead spirits believed to visit the living in the first days of November. More than 100 kids also staying in the shelter where he has lived for the past year and a half did the same. Jefferson wore a bright smile under his makeup, running between groups of friends in the auditorium as the offerings were judged.

The shelter was the most stable home the teen — who chose the pseudonym Jefferson to keep his real name private — had known. His mother kicked him out of their home in rural El Salvador when he was 11 because he had started wearing women's clothes. "She realized this is how I was and she beat me, saying, 'I'd rather have a crazy person in my house than a gay one,'" Jefferson said. Jefferson survived as a prostitute on the streets of the capital San Salvador for three months, until his mother got sick with an illness that paralyzed her face and forced him to return home to support her. As her situation deteriorated, his cross-dressing caught the attention of some of the gang members in his neighborhood. Gangs have grown into large organized crime syndicates in Central America over the past 20 years, thanks in large part to the U.S. policy of deporting immigrants who had been part of gangs like MS13 in Los Angeles. The gang members told him they didn't like seeing people like him "contaminating the neighborhood," beat him up, and pressured him into working for them, though he didn't say what work he did.

On Feb. 19, 2012, gang members beat him up yet again. The same night, his mother took herself to the hospital. That's when he decided to head to the United States.

"I decided it was better to get out," he said.

Jefferson decided to make the trip north around the same time more and more kids from El Salvador, Guatemala, and Honduras were doing the same, sometimes at their parents' urging. These three countries alone make up 93% of the more than 60,000 children who attempted to enter the United States on their own in 2014. The explosion in the number of unaccompanied child migrants — rapidly rising from fewer than 20,000 in 2011 — has largely been driven by gang violence, political instability, and extreme poverty within their borders.

Human rights activists say these countries also have some of the highest rates of anti-LGBT violence in the Americas — especially targeting trans women — although comprehensive hate crime statistics are not readily available. The Salvadoran trans advocacy organization COMCAVIS has documented 14 murders of LGBT people this year; 12 were trans women and two were gay men. One survey of trans women in El Salvador found that 87% knew at least one trans woman who had been murdered, and not a single case in which the killers had been arrested.

LGBT kids head north in search of the same stability and security as other migrant children. But they also seek a kind of love and acceptance that seems unimaginable at home.

Jefferson remembered telling his mother as he left, "I am sick of my family. I want a better family."

Jefferson began walking toward Guatemala that night in February 2012 with almost no money in his pockets, "maybe 10 cents." He was vague about what happened before he reached Guatemala, but it took almost a year before he made it out of El Salvador. He said he walked and hitchhiked. Sometimes the truck drivers who gave him rides would also feed him, but he mostly slept on the street.

He had some luck when he entered Guatemala and found someone to take him all the way to the Mexican border in just one day. He slipped into Chiapas and stayed in a shelter for migrants while begging on the street to raise enough money to pay for a seat on the minibuses that transport migrants north to the U.S. He eventually made it on one — but the bus was promptly stopped by immigration police. They told Jefferson they were going to send him back to El Salvador.

Jefferson said he told the officers, "I can't go back to my country because I … faced death threats. ... After what I've done, they're not going to forgive me."

Jefferson had a strong claim against deportation: Both the U.S. and Mexico clearly recognize LGBT people as part of a social group that have grounds for political asylum, unlike people who are fleeing poverty or gang violence. Instead of being sent home, Jefferson's case was referred to the Mexican agency that grants humanitarian visas, known as COMAR, and he was taken to a detention facility in the city of Palenque to wait for their decision.

Advocates say most LGBT migrants don't petition for asylum in Mexico, largely because it doesn't promise the same work opportunities as the U.S., and Mexico also has high rates of anti-LGBT violence. (Advocates who work with LGBT people seeking asylum in the U.S. say that Mexico is among the most common countries their clients are fleeing.) But others simply don't know they have the right to petition or fail to navigate complicated legal processes that even many adults don't understand. Even in the U.S., where there are many programs to connect unaccompanied minors with immigration lawyers, only a relatively small number of asylum cases are filed — less than 3 percent of the children estimated to have entered the U.S. in the past year have petitioned for asylum, according to statistics from the Department of Homeland Security.

And law enforcement can pose special dangers for LGBT migrants. One 16-year-old trans girl from El Salvador who was deported earlier this year after being caught by Mexico City police reported to the El Salvadoran trans rights group COMCAVIS that she was gang raped by officers while in detention. Jefferson also said he was raped during his nearly three months in detention.

Though he was only 15, Jefferson was placed in a facility with adult men and says he was told there were no separate facilities for children. He says there were no guards inside the facility who could protect him; only the perimeter of the facility was guarded. So when he started being harassed, there was no one he could turn to.

"There were two," he said. "One closed the door, and the other…"

He said he tried to tell those in charge what was happening, but "they didn't do anything" except arrange for him to see a doctor and a psychologist and tried to broker a dialogue between him and his attacker. "They told me that he wanted to talk to me, but I didn't want to do it," he said.

Jefferson's story has a mostly happy ending — at least temporarily.

He was ultimately granted the right to stay in Mexico. After nearly three months, COMAR granted him a visa and he was taken to the airport. Those in charge wouldn't tell him where he was going — a technique to ensure that the men who had assaulted him inside the detention center would not be able to find him, he was later told. The flight to Mexico City was the first time he'd been on an airplane. The flight, he said, was "bone-chilling."

They took him to the shelter where he now lives, which houses both Mexican and migrant children who have no homes. It is affiliated with the global organization Covenant House International, but its management has asked that BuzzFeed News not publish its name for Jefferson's security.

Five boys he had met in the detention center were already living at the shelter, and being reunited with them was like coming home — but to a family that actually loved him. "I felt, like, even better than I did with my family, because my family never gave me even a hug or a toy," Jefferson said. Since the group of boys were reunited at the shelter, "we love each other as if we are brothers."

Life isn't perfect there — he has to wear boy's clothes and keep his hair short. A spokeswoman for the shelter said this was for his own safety because "unfortunately Mexican society faces some scenarios which are not LGBT-friendly."

But Jefferson said this "isn't a problem," especially since he's only a year away from being 18, when he will be able to live as he choses. He's been out to the other kids since the day he arrived and never had any problems, he said, and there is at least one other LGBT teen who lives there. Jefferson is finishing high school and studying how to cook, make clothes, and do makeup.

"Overall, I'm doing very well," he said.

When Jefferson becomes an adult in the eyes of the law, he plans to pick up where he left off and finish his journey to the U.S., even though he has a permit to stay in Mexico. If he makes it, he risks being put into a U.S. detention center, where harassment and violence targeting LGBT people has been such a serious problem that a civil rights group filed a mass civil rights complaint against the Department of Homeland Security in 2011. In addition to proving why he can't return to El Salvador, he'll also have to make a case for why he cannot stay in Mexico, because once a refugee is given safe harbor by another country, they're ineligible for asylum in the United States. And while there are many programs to get legal services to child immigrants, adults are not so lucky — they have to find a lawyer on their own, and there's no guarantee of legal representation for people facing deportation the way there is for defendants facing criminal charges.

Jefferson said too much of Mexico is just as dangerous as El Salvador. He also worries that he won't be able to earn enough money there. Despite his harsh words to his mother when he left, he says part of his reason for leaving is that he didn't want her to worry about his problems with the gangs as she struggled with her health. He's hoping that in the U.S., his diploma from the sewing school will let him find "better work [to pay for a] cure for my mother's disease."

But this time, he said, he would be determined to make the trip different than the one that brought him to Mexico City.

"I don't want to go back to what I came from, traveling in a trailer, hitchhiking," he said. "I endured hunger, cold, punches, humiliation from people. I've had enough of traveling by land."

He plans to fly.
