Gregory Jonas, a 59-year-old African American male, was a dedicated police officer with the Centreville Police Department in Illinois.

The incident occurred around 2:00 am when Jonas was questioning an individual. He was shot in the head and died at the scene. The suspect, Lemuel A. Houston, was later apprehended and charged with first-degree murder. Houston, who was 22 years old at the time, pleaded "guilty but mentally ill" to the murder on June 13, 2012, and was sentenced to 53 years in prison without parole.
