Investigators have released new photos and leads in the mysterious case of a Barrow County woman who disappeared for several days before she was found murdered more than 100 miles from home.

Murder warrants were issued for four suspects Saturday in the case of 37-year-old Rossana Delgado’s killing, and the GBI released photos of a fifth suspect Sunday.

No further details on the fifth suspect have been released, but on Tuesday the GBI released new photos of a woman thought to be one of the last people to interact with Delgado while she was alive.

The GBI said the photo of the woman was taken from security footage filmed April 16 in a store at Plaza Fiesta in DeKalb County, the same day Delgado was reported missing. The agency is requesting the public’s help in identifying both individuals in the recently released photos.

The four original suspects are still wanted, and the GBI and other agencies are actively searching for them. They are Megan Alyssa Colone, 30, of Stone Mountain; Juan Ayala-Rodriguez, 35, of Gainesville; Oscar Manuel Garcia, 26, of Austell; and Mario Alberto Barbosa-Juarez, 29, of Oklahoma City, Oklahoma.

According to the GBI, the suspects all may have fled Georgia. Colone, the only female suspect, could be traveling under the alias Grace Beda and accompanied by minor children. An alert about the suspects has been sent to law enforcement agencies nationwide.

Delgado, a married mother of two, was working as a rideshare driver the day of her disappearance, her husband Johnny Castro told Channel 2 Action News. He was able to track Delgado’s cellphone location, which took him to a home in Decatur, he said. There, he found a mask with blood on it, Castro told Channel 2.

The GBI has not released information about the nature of Delgado’s death, but said an autopsy is pending. Her body was found in Gilmer County in northwest Georgia.

Anyone with information about the whereabouts of the suspects or the identities of the people shown in the recently released photos is asked to call the GBI tip line at 1-800-597-TIPS (8477) or report the information online.
