Authorities on Tuesday arrested a man in the case of a Georgia 911 operator who vanished March 21, according to MyFoxAtlanta.com.

Walker County, Ga., Sheriff Steve Wilson said LaFayette police officer Harbin Chaffin was nabbed on three felony warrants obtained by the state Bureau of Investigation in connection with the disappearance of Theresa Parker, 41.

Chaffin was arrested in Mobile, Al., on one count violation of oath by a public officer, one count tampering with evidence and one count computer invasion privacy.

He had already been arrested once in the case. In April, officials charged him with making false statements to police.

Theresa's husband, Sam, is a sergeant on the same police force as Chaffin. Chaffin is the next-in-line supervisor on the same shift as Sam Parker.

Theresa and her husband were in the midst of a divorce when she vanished. Parker has been suspended from his job as a sergeant with the LaFayette Police Department during the investigation. Sam Parker was not staying at the couple’s home when Theresa disappeared, and Theresa was packing up the house and moving to a home she found to rent in Fort Oglethorpe.

Investigators say Sam Parker has been cooperative but label him as a "person of interest." He has told local FOX affiliate WAGA that he believes his wife ran off after being caught in an affair. Authorities told FOXNews.com there was no evidence of that, and Theresa Parker's family has said they don't believe her husband's story.

Parker is white with short brown hair, brown eyes and glasses. She’s about 5 feet, 7 inches tall and weighs 125 pounds. She has been missing since the evening of March 21, when she left her sister's home. Parker’s SUV was found at her home the morning of March 22.

Police encourage anyone with any information about Parker’s whereabouts to call a 24-hour tip line at (706) 639-2255.
