Fernando Casas was 19 when he was reported missing on May 9, 2016, from Stone Park, Illinois. His remains were found May 30, 2016, in a plastic bag in Thatcher Woods Forest Preserve. The Cook County Medical Examiner determined he died of a gunshot wound and ruled the death a homicide.

Detectives identified 36-year-old Carlos Martinez-Rodriguez as the primary suspect; he was last seen with Casas before the disappearance. An arrest warrant for Martinez-Rodriguez was issued September 6, 2016. He was located in New York City and returned to Cook County on January 5, 2017, then charged with first-degree murder. He was denied bond at his initial appearance at the Maywood Courthouse and was scheduled for further court proceedings.

Did anyone in the Stone Park or Thatcher Woods areas see Fernando or his car in early May 2016, or have information about his last known movements?
