Joseph Caffarello, 31, died of a gunshot wound to the chest on January 7, 2015, in Rosemont, Illinois. The Cook County medical examiner ruled the death a homicide. The shooting occurred after a domestic dispute between Caffarello and his wife, Deanna Caffarello, at their home in a gated community.

Deanna’s brother, off-duty Rosemont police officer Rick Drehobl, drove Deanna and her baby away from the residence; Joseph pursued them and the vehicles collided on Scott Street. After the crash Drehobl shot Caffarello, who was pronounced dead at the scene. The Illinois State Police investigated and the Cook County State’s Attorney’s Office reviewed the case but declined to file criminal charges, citing insufficient evidence. Drehobl, placed on desk duty during the investigation, later returned to regular patrol.

Caffarello’s history included multiple domestic disputes with his wife, a prior firing as an Illinois Tollway garage supervisor for misconduct, and family ties to Anthony Jeep Daddino, described as a mob street tax collector. Does anyone have information about the events that led up to the collision on Scott Street?
