"We have not given up hope that he will soon be found", Schuchat wrote. O'Connor was sure Cunningham was upset over the lack of promotion because he allegedly shared the news with co-workers.
Atlanta Police said that Cunningham was told he wouldn't receive a promotion a week before he went missing.
Initial reports by Atlanta police indicated that Cunningham, 35, vanished without a trace February 12 after being turned down for a promotion.
Although the CDC's prepared statement on Timothy Cunningham's disappearance maintained that issues with a potential promotion were not involved, another Atlanta police officer disputed that on Monday, not long after the statement was released. Crime Stoppers said the money is for information "that points to criminal activity in the disappearance".
"In fact", the CDC statement continued, "he received an early promotion/exceptional proficiency promotion to Commander effective July 1, 2017, in recognition of his exemplary performance".
On Tuesday, Atlanta police spokesman D.T. Hannah said in a statement: "We stand behind every statement the Atlanta Police Department made about Dr. Cunningham's employment, as our information came directly from the CDC".
The unusual circumstances surrounding Cunningham's disappearance have continued to baffle authorities.
When they arrived at his Atlanta home on February 14, the couple found their son's phone, keys, wallet, vehicle and dog, with no trace of him in sight. "If anyone reading this has information about the whereabouts of Commander Cunningham, please come forward".
A GoFundMe page has brought in more than $24,000 to establish a reward for information that might lead to Dr. Cunningham.
"Over and above any of his assignments at CDC, his early promotion within the USPHS reflects his excellence as an officer and an employee", the statement read.
Adding even more mystery to the freaky case, Chris Torry, a neighbor of Cunningham's, told WAGA that the CDC employee made a unusual request a few days before he disappeared.
