A dramatic turn of events unfolded in the investigation of the shooting deaths of an Illinois family of four, as a person connected to a vehicle believed to be linked to the crime died in a police pursuit in Oklahoma, per CNN.

The suspected murderer, who was behind the wheel of the vehicle with the license plate connected to the Illinois family's shooting, crashed the vehicle during a police chase in Catoosa, Oklahoma.

The vehicle subsequently caught fire, and authorities discovered the male suspect dead in the driver's seat with a gunshot wound, according to Chris Burne, deputy chief of police in Romeoville, Illinois.

A female passenger in the vehicle also had a gunshot wound, as reported by Burne.

The license plate of the vehicle was identified as being linked to a suspect in the shooting deaths of the Illinois family in Romeoville, located around 30 miles southwest of Chicago.
