A 51-year-old man was stabbed to death in the West Ridge neighborhood Thursday morning.
Timothy W. Quirk got into an argument in the 2200 block of West Farwell Avenue about 6:15 a.m. Thursday, authorities said.
The argument escalated and Quirk was stabbed in the neck, authorities said.
Quirk, who lived on the block, died at the scene, according to the Cook County medical examiner's office, which ruled the death a homicide.
A police source said both people involved in the dispute had been drinking, and Area North detectives are investigating the attack as a domestic stabbing. The relationship between the two was not immediately available.
Detectives are speaking with a person of interest, but no charges have been filed as of Friday afternoon.
