A Tinley Park man has been extradited to Chicago and ordered held without pretrial release in connection with a deadly shooting that left a concealed-carry holder dead in Gresham, prosecutors said.
Essian Anthony McGinnis, 34, faces a charge of first-degree murder in the May 11 killing of 42-year-old Angelo Seabrook outside a party in the 7500 block of South Normal.
According to a detention petition filed by prosecutors, McGinnis and Seabrook argued during a party at the home earlier that evening. Seabrook left after the dispute but came back later that night. Around 10 p.m., he stepped outside and walked toward McGinnis, who was standing on the sidewalk with three other people.
Seabrook was about ten feet from McGinnis, and both men were armed. However, Seabrook—who had a valid concealed carry license—never removed his weapon from its holster, according to prosecutors. They said none of the witnesses saw him reach for or brandish the gun.

Prosecutors allege McGinnis pulled out a handgun and shot Seabrook twice in the chest. As Seabrook crouched down, McGinnis “unloaded his entire clip” into him, the petition said. A total of 16 shell casings, all fired from the same weapon, were recovered at the scene.
Seabrook was found with his gun still holstered in his front waistband. The firearm was fully loaded and had been struck by a bullet, which rendered it inoperable, prosecutors said.
McGinnis allegedly fled the scene in a car with his girlfriend and their 10-year-old child. The filing states the woman had arrived an hour earlier to pick him up and had also helped a paraplegic partygoer into the vehicle as they waited.
During the drive home, McGinnis allegedly “made admissions” to his girlfriend about the shooting, claiming Seabrook had been “clutching,” prosecutors said.
Phone data placed McGinnis near the scene of the murder at the time of the shooting. McGinnis, who worked as a truck driver, was taken into custody in Nebraska on June 11, the same day a Cook County judge filed an arrest warrant in the murder case. He was then returned to Chicago.
Cook County Judge Deidre Dyer granted the state’s detention petition, describing his alleged actions as “sudden and egregious.”
