Authorities have partially solved the mysterious disappearance of a Centers for Disease Control and Prevention employee with the discovery of his body. But they may never know how he drowned in a river not far from his home. Fishermen found Timothy Cunningham's body on Tuesday partially submerged in water and mud on the west bank of the Chattahoochee River in Atlanta, fire-rescue department spokesman Sgt. Cortez Stafford said at a news conference. Fulton County Chief Medical Examiner Jan Gorniak determined the cause of death as drowning, but said she couldn't provide additional information because she was still awaiting toxicology reports. "Since the investigation is ongoing, we do not have ... whether it was an accident, a suicide, or anything other than that" Cunningham drowned, Gorniak said at the news conference Thursday. Maj. Michael O'Connor of the Atlanta Police Department's Major Crimes Section said Thursday that investigators had spoken to everyone of importance and that barring any new information, "this case will likely close fairly soon." Cunningham, 35, was an epidemiologist at the Atlanta-based federal agency. He disappeared Feb. 12. His family reported him missing on Feb. 16 after going to his home and finding his belongings and vehicle there.
