Immigration officials were not to blame for the deaths of two migrant children while in US custody last December, a government watchdog has ruled. The Inspector General for the Department of Homeland Security “found no misconduct or malfeasance by DHS personnel” in the deaths of Jakelin Amei Rosmery Caal Maquin, age 7, and Felipe Gomez Alonso, 8, according to statements released Friday. Both children died of sepsis, investigators said, after illegally crossing the US-Mexico border with family members.
