Dr. Xu Wang was a 39-year-old physician who disappeared on the morning of August 10, 1999, after leaving her Darien, Illinois, home for a shift at Rush-Copley Medical Center in Aurora. She was reportedly wearing medical scrubs and never arrived at the hospital. Her husband, also a physician and disabled with Parkinson’s Disease, reported her missing on August 11th.

Hours after the report, Dr. Wang’s red 1994 Toyota Camry was found locked and abandoned on a gravel parking strip near the Waterfall Glen Forest Preserve, about five miles from her home. Her backpack with credit cards remained inside. Less than a week later her pager was recovered in weeds off Cass Avenue near Interstate 55, roughly one mile north of where the car was located; the pager was still turned on but yielded no location leads. Friends said the couple had been planning to divorce, while her husband described the marriage as happy and has maintained his innocence; investigators considered him a suspect.

Human remains recovered in the area on separate occasions were ultimately not identified as hers. What happened to Dr. Wang that August morning remains unknown. If anyone knew Dr. Xu Wang, her routines, travel on August 10, 1999, or has information about the areas around Waterfall Glen or Cass Avenue that day, please come forward.
