Three people are hospitalized with gunshot wounds, all in critical condition, after a shooting at a party early Sunday morning at 885 Regent Drive.

The gunman is still at large.

The DeKalb Fire Department responded about 1:37 a.m., transporting the three male victims to Kishwaukee Community Hospital. One of the victims, 25, was transferred to Good Samaritan Hospital in Downers Grove. Kishwaukee spokesman Mike Kokott said the other two victims, a 21-year-old and a 19-year-old, remain in critical condition in DeKalb.

Police Chief Bill Feithen said none of the victims were NIU students. Investigators determined that an argument broke out during the party and someone involved began shooting as he was leaving the building.

Police describe the primary suspect as a 6-foot-tall black male in his late teens or early 20s wearing a black puffy coat and black pants. Police also are looking for another black man wearing a powder blue outfit who possibly accompanied the primary suspect.

Feithen said investigators are searching for two vehicles seen leaving the scene.

“We are currently trying to track down a green Navigator with possible damage to the taillight and front damage,” he said. “We are also looking for a black SUV (sport-utility vehicle).”

An eyewitness who spoke on condition of anonymity said the suspect left in a sport-utility style vehicle as another, smaller car left the scene. The witness, who lives in the same apartment complex as the shooting, was not home at the time but saw the aftermath of the party when she returned.
