A person of interest was in custody after a fatal shooting during an argument in Lincoln Park late last month, Chicago police confirmed Thursday morning.
Charges have not been announced.
Authorities released photos and videos of the alleged gunman Tuesday asking for help identifying him. Footage from a surveillance camera shows him dressed in all black.
About 4 p.m. on Nov. 27, 34-year-old Alexander Nesteruk was “exhibiting erratic and dangerous behavior” in the 2400 block of North Clark Street when he instigated an argument with a group of people, one of whom pulled out a gun and fired shots, Chicago police and Ald. Timmy Knudsen (43rd) said.
Nesteruk suffered a gunshot wound to the chest and was taken initially in critical condition to Illinois Masonic Medical Center. Nesteruk, of Wheaton, was pronounced dead at 1:19 p.m. Monday, according to the Cook County medical examiner’s office.
The investigation is ongoing, police said.
