The girl’s body was discovered in an alleyway near 20th Avenue and Pennsylvania Street by utility workers on the morning of Monday, Sept. 16.

Her body – initially described as a teenage Jane Doe – was discovered in an alleyway near 20th Avenue and Pennsylvania Street by utility workers on the morning Sept. 16.

Their coworkers said the teen was found tied to a newly-placed utility pole, and they believed she was beaten to death. But a Medico-Legal Death Investigation Team from the Coroner’s office ruled that the girl had died of a gunshot wound, and said she was not found tied to a utility pole.

The manner of the girl’s death was a homicide.

In a statement, Lake County, Indiana Sheriff Oscar Martinez Jr. said his department was actively pursuing several leads on both sides of the Illinois-Indiana state line in search of suspects and information.
