Investigators say a former co-owner traveled to Dockers restaurant in Fox Lake and shot his brother, who is the current owner, multiple times before fatally shooting himself.

The Fox Lake Police Department and Fox Lake Fire Protection District responded around 1:05 p.m. Tuesday to Dockers, 33 West Grand Avenue in Fox Lake, for a report of a person shot.

Lake County Major Crime Task Force Spokesman Christopher Covelli said a preliminary investigation shows a 63-year-old man traveled to the restaurant, which his brother, a 56-year-old, still owns.

The 63-year-old man intended to confront his brother about an ongoing feud, Covelli said.

An argument ensued in the kitchen and the 63-year-old man pulled out a gun and shot his brother.

The 56-year-old man was able to flee outside but his brother followed him and continued shooting at him, Covelli said.

The 56-year-old collapsed outside after he was shot multiple times.

Covelli said the 63-year-old man fatally shot himself just outside of the restaurant before police arrived. His identity is being withheld pending family notification.

The 56-year-old man was transported by ambulance to Advocate Condell Medical Center in Libertyville. He remains in critical condition.

Fox Lake Police Chief Jimmy Lee said many of the patrons at the restaurant reported not knowing what was going on at the time of the incident.

A group of patrons told officers they were not being served after being seated so they got up and left.

Some patrons thought they heard construction noise and others described it as gunshots, Lee said.
