An off-duty Chicago police officer died late Sunday night after collapsing in an apartment hallway, apparently of natural causes, authorities said.
The 54-year-old officer, identified by police as Detective Patrick Finucane, was discovered unresponsive in an apartment complex in the 700 block of South Wells Street in the South Loop neighborhood shortly before 10:15 p.m., Chicago Police Department News Affairs Officer Ron Gaines said.
He was pronounced dead at the scene at 10:40 p.m., according to the Cook County medical examiner's office.
Police will be conducting a routine investigation, but the death "doesn't appear to be suspicious in nature," Gaines said.
Security footage in the building showed the officer clutch his chest while walking down a first-floor hallway and then fall to the ground, police said.
Police said the officer was a detective and a 30-year veteran of the police department.
In a statement from the department's Office of News affairs, police said, "Detective Finucane was a respected and dedicated member of the Chicago Police Department for 30 years, working tirelessly for both the city of Chicago and on behalf of the Chicago Police Memorial Foundation. We extend our sincere condolences to his family, friends and colleagues during this difficult time."
As is customary for fallen police officers and firefighters, the officer's body was accompanied to the medical examiner's office by a procession of fellow officers.
