A 14-year-old Indianapolis girl has been charged as an adult in the fatal stabbing of her 4-year-old cousin.

Brienne Delaney, spokeswoman for the Marion County Prosecutor's Office, says the adult murder charge was filed against the girl Wednesday in juvenile court in Indianapolis. A juvenile court judge must decide whether to move the case to adult court.

Leon Thomas III., was found bleeding from stab wounds Saturday at an Indianapolis apartment and later died at the hospital. Police say they found the girl covered in blood and walking along a nearby street.

Delaney said it's "very rare" for the prosecutor's office to charge a juvenile with murder. Among the 3,500 to 4,000 juvenile cases the agency handles each year, she said typically only one involves a murder charge.
