An official cause and manner of death in the homicide investigation of 3-year-old Ella Camp is expected within 30 days, authorities said.

Ella died Sept. 19 after being rushed to Children’s at Scottish Rite Pediatric Hospital in Atlanta. 

David Zachary Gresham, the 20-year-old boyfriend of Ella’s mother at the time, faces a murder charge in connection with the girl’s death. Police have said there are no other suspects in the homicide investigation.

The official cause and manner of Ella’s death — why she died and under what circumstances — remain unknown.

“The official cause and manner have not been determined,” Coroner Barry Henderson said.

The time needed to determine autopsy results varies, Henderson said. Results for a heart attack victim might take 10 days.

“In a case like this, it takes longer,” Henderson said.

According to police reports, Gresham had been with Ella on Sept. 17 before he took the girl and her family to Floyd Medical Center about 11:25 a.m. that day. Ella was unresponsive and had extreme head trauma.

Gresham then left the area and was not located at the time, reports state.

Ella was flown that day to Children’s at Scottish Rite Pediatric Hospital.

Gresham was arrested Sept. 18 on a probation warrant. Ella died the following day.

Initially held in the Floyd County Jail, Gresham is now incarcerated without bond at the Polk County Jail.
