A blood-stained pocket knife was hurled onto the shoulder of the Eisenhower Expressway after the fatal stabbing of a 64-year-old laborer in a Near West Side alley Monday morning.
Meanwhile, police said a person of interest remains in custody Tuesday and no charges have been filed.
Surveillance footage captured the alleged attacker fleeing the scene in the 2400 block of West Gladys Avenue and throwing an apparent blood-stained pocket knife onto the westbound lanes of the Eisenhower near the 2500 block of West Van Buren Street, according to a Chicago police report. Police also recovered a jacket and glove apparently belonging to the attacker.
A motive was not disclosed by police for the stabbing, which happened around 7:50 a.m. Monday at the Gladys Avenue address when the attacker approached the 64-year-old victim, whose name was not being released immediately, and the two began arguing, Chicago police said.
During the argument, the attacker stabbed the man multiple times in the chest and back and responding officers found the victim lying face-up on the ground, according to police reports obtained by the Chicago Sun-Times.
The victim, of the city’s Humboldt Park neighborhood, was taken to Stroger Hospital where he was pronounced dead at 8:55 a.m., according to the Cook County medical examiner’s office.
The person of interest was taken into custody at a bus stop near Madison Street and Western Avenue, officials said.
Area 4 detectives are investigating.
