About 7 a.m. on Friday, officers responded to a 911 call from a resident who saw a woman’s body in their backyard. Police found 18-year-old Karalynn McNicholas, who was initially thought to be between 30 and 40 years old, unresponsive in the 6100 block of South Maplewood. She was pronounced dead at the scene, Chicago Police said. She had no visible signs of trauma.
