A US Centers for Disease Control and Prevention (CDC) doctor's body was discovered in a Georgia river after he had disappeared in February, police said Thursday.
Cunningham, who went home sick from work on February 12, had also apparently left behind his dog, wallet, auto and phone in his home, which alarmed his parents, who had traveled to Atlanta from Maryland to check on him, police said.
His family said he called out sick from work and was not seen or heard from since that day.
Authorities have scheduled a news conference for 2 p.m.
During a news conference, police said there is no indication of foul play, and while they are still waiting on a final report from the medical examiner, it appears that Cunningham drowned.
The manner of death has not been determined at this time, the medical examiner said.
It's not clear where Cunningham entered the river, which had been previously searched, officials said. "There's just no way to tell due to the rise and fall of the river", Stafford said.
The agency also closed with a message to Cunningham directly.More news: Federal Judge Orders Texas To Comply With Voter Registration Laws

The pet, along with Mr Cunningham's keys, wallet, phone, identification, credit cards and passport were all found by investigators safely locked in his Atlanta home. A boat was used to access the body. Cunningham was also known to be a jogger, and was wearing his "favorite jogging shoes" when he was found.
"At this point, we have no indicators of foul play", he reiterated. "None of those items are missing", O'Connor said.
Cunningham, who has two advanced degrees from Harvard University, studied the health differences between people from various backgrounds, including race, gender, geography and class, according to his biography on the CDC's website.
The 35-year-old had reportedly worked as a commander in the U.S. Public Health Service and had responded to the Ebola virus and the Zika virus outbreaks.
Police and the CDC released conflicting information about Cunningham in the days after his disappearance.
On the morning of the disappearance, he said, Cunningham was informed by his supervisor as to why he wasn't receiving a promotion at work.
"As many of his colleagues in the USPHS have pointed out, this information is incorrect".
