CBP Says that the reason they did not reveal details sooner was out of respect to the family of the little girl.
Adding that border patrol agents, including EMT, did everything in their power to save Jakelin.
In a statement CBP says,
“The agents involved are deeply affected and empathize with the father over the loss of his daughter. we cannot stress enough the dangers posed by traveling long distances, in crowded transportation, or in the natural elements through remote desert areas without food, water, and other supplies.”
