The authorities in Atlanta announced a $10,000 reward for information leading to an arrest and indictment in the case of a missing Centers for Disease Control and Prevention employee who disappeared about two weeks ago.

The employee, Timothy J. Cunningham, 35, was promoted to commander in the United States Public Health Service in July, his family said. According to the police, he was last seen on Feb. 12.

“I feel like I’m in a horrible ‘Black Mirror’ episode,” Commander Cunningham’s sister, Tiara Cunningham, said in a phone interview on Saturday. “I’m kind of lost without him, to be quite honest.”

Ms. Cunningham, 27, was the last family member to speak with Commander Cunningham before he went missing, she said.
