U.S. marshals are looking for a woman accused of killing her infant daughter, who is believed to be living with her father, who is also wanted on armed robbery charges.

Estefania Roman-Aguilar, 19, is wanted in the Sept. 21, 2016, murder of her five-month-old daughter.

Brookhaven police responded to a medical call on Buford Highway where they found the child unresponsive. Police said they tried to revive the girl, who was pronounced dead on arrival at Scottish Rite Hospital. The official cause of death was suffocation.

A subsequent investigation resulted in evidence of a homicide. Roman-Aguilar was charged with murder in November 2016.

Roman-Aguilar's father, Jose Hilario-Gomez, 40, is wanted in DeKalb County for a 2015 armed robbery.
