PHOENIX -- A man wanted in the February death of his girlfriend's 2-year-old son is now in custody.
According to a spokesman for the Phoenix Police Department, Juan Garcia, 18, turned himself into U.S. Immigration and Customs Enforcement agents near the Lukeville, Ariz. - Mexico border crossing point.
He is currently being held at the Pima County Detention Center awaiting a transfer to Phoenix.
On February 24, Garcia's girlfriend, the victim's mother, 18-year-old Wendy Rogel-Pagas, dialed 911 because her son was not breathing.
When emergency crews arrived at the home near 39th Avenue and Encanto Boulevard, the child was pronounced dead at the scene.
Police said 2-year-old Jorge I. Zamora-Rogel had evidence of trauma to his head and body.
At the time, police said, Garcia "picked him up by his throat, literally, and began smashing his head against a bedroom wall."
Police said Garcia left the home then came back and continued beating the boy.
The boy's mother was arrested on child abuse charges. Police said she watched the beating occur but did not seek help or medical attention until it was too late.
