Two men were fatally shot Tuesday afternoon by a former employee of a Navy Pier subcontractor, according to Chief of Patrol Jon Hein, who spoke at a press conference.

The tragic incident occurred around 1:30 p.m. near a restricted loading dock area on the north side of Chicago’s Navy Pier at 600 East Grand Avenue, a location not accessible to the general public.

The victims, identified as Antwon Johnson, 47, and Peter Jennings, 51, were taken to Northwestern Memorial Hospital, where they were pronounced dead shortly after arrival.

Hein described the suspect as a “disgruntled ex-employee,” and police confirmed they have a “person of interest” in mind who is actively being sought in connection to the shooting.

Sources told Channel2 NOW that suspect has been taken into custody.

Following the incident, Navy Pier’s Chief Operating Officer Brian Murphy activated an immediate lockdown alert, sending a shelter-in-place order to the pier’s 70 tenants through an internal communications system.

This precautionary measure has since been lifted, and Murphy emphasized that at no point was the general public at risk.

“This was an isolated incident,” Murphy said, expressing condolences for the employees who lost their lives during what should have been a routine workday.

Chief Hein reinforced this, adding, “The pier is clear now. The pier is safe.”

Authorities are continuing their search for the suspect as they investigate the events leading up to this tragic shooting.
