The Alameda County Social Services Agency (the Agency) filed a petition under Welfare and Institutions Code section 300, subdivision (b) (section 300(b)) alleging the failure or inability of appellant Nelson B.’s parent or legal guardian to supervise or protect him adequately. Appellant, then age 16, was a runaway living with his girlfriend’s family in Oakland. He was bom in Honduras and entered the country illegally on his own in 2009. United States Immigration and Customs Enforcement (ICE) apprehended appellant and placed him in the custody of his aunt in Maryland, where he lived and attended school for at least six months before running away to California in 2011.
