Jackelin Caal, the 7-year-old who died in Border Patrol custody this month after crossing into the United States through the New Mexico desert with her father, didnt make her dangerous and ultimately fatal journey to this country alone.

Some 161 other migrants, including about 50 children traveling alone, were in the group that crossed through the desert with Caal and her father to the remote outpost of Antelope Wells in New Mexico.

Many migrants know that pushing into far-flung crossings over rough terrain means taking huge risks. But U.S. government policy has left them few other options: As President Donald Trumps administration has made it harder to request asylum at legal ports of entry and deployed the military to the border to scare away asylum-seekers, migrant families are crossing in more isolated and treacherous areas.
