A man hit by a vehicle last month in the South Chicago neighborhood died of cancer three days after the hit-and-run crash, authorities have determined.
About 10:45 p.m. on Aug. 21, 50-year-old Robert Davis, was walking in a crosswalk at Commercial Avenue and 91st Street when he was struck by a westbound Acura RL, police and the Cook County medical examiner’s office said.
After striking Davis, the driver continued west on 91st Street and was seen several minutes later driving north on Houston Avenue, police said.
Davis, of the Calumet Heights neighborhood, died three days later at University of Chicago Medical Center, according to the medical examiner’s office.
An autopsy did not initially rule on the cause and manner of Davis’ death, but investigators later found his primary cause of death was metastatic malignancy, probably in his lung, according to the medical examiner’s office. Cirrhosis of the liver and blunt force trauma from the crash were listed as contributing factors and his death was ruled an accident.
Police said the investigation was ongoing as of Tuesday afternoon.
Anyone with information was asked to call the Major Accidents Investigation Unit at (312) 745-4521.
