Sheffield came to the residence shortly before the shooting happened, the teen’s family told police. Police said there was an active protection order against him through the Fulton County court system.

“Family members, who were upstairs in the residence with the couple’s 8-month-old child, went to investigate the sound of gunfire downstairs and found both parties laying on the floor of the home, suffering from gunshot wounds,” Marbury said. “The preliminary investigation revealed that the male shot the female before turning the gun on himself.”

Sannoh was pronounced dead at a hospital shortly after 11 a.m.

The child is with her family, police said.

According to a GoFundMe page set up for Sannoh, she came to the United States from West Africa in 2005 and attended Riverdale High School.

However, Sannoh was no longer enrolled in the school, Clayton County Public Schools spokeswoman Jada Dawkins told AJC.com.

“While the district is saddened to learn the news about this incident,” Dawkins said, “the school district has no further comment as our thoughts and prayers are extended to the family during this difficult time.”
