U.S. Border Patrol officials are trying to reunite a pair of young sisters with their family after the two girls were found alone, wandering the area between the U.S. and Mexico border in Arizona.

Agents found the girls, ages 4 and 6, in a marsh area near the Colorado River in Yuma.

According to the U.S. Border Patrol Yuma Sector, the area “is an often used-crossing point by unaccompanied migrant juveniles.”

“A Yuma Sector agent, concerned about their safety, quickly approached the young girls, and escorted them to safer terrain,” the post said, adding the girls had a note that contained contact information for their “tia,” or aunt.

“The girls were taken into custody and attempts will be made to reunite them with family,” a Facebook post by the Yuma Sector officials said.

While agents didn’t specify what would happen to the girls as officials search for their relatives, current precedent would indicate the sisters will be held in protective custody and then moved to shelters run by the Department of Health and Human Services, CNN reported.

From there, they will await release to sponsors in the U.S. interior.
