Josephina Ramirez, 16, pleaded guilty Friday to attempted murder and assault in the death of 13-year-old Julio Marquez.
Marquez was found shot and beaten to death on Northeast Halsey Street in November 2011.
Police arrested Ramirez and two teenage boys in January of 2012 after a two-and-a-half month-long investigation.
According to her plea deal, Ramirez will spend 15 years in prison, but only if she helps in the prosecution of her co-conspirators.
