A Georgia man has turned himself in to police after shooting his ex-wife and former stepdaughter Tuesday morning.

Terrance Sherrod Roberson opened fire outside of the Little Mountain Christian Academy in Stockbridge, where the woman was dropping off her 10-year-old daughter, the Rockdale Citizen reported.

The little girl routinely takes a bus from the daycare to Lorraine Elementary.

The woman and her daughter got to the daycare around 6:30 a.m. when they heard gunshots, the AP reported.

She heard gunshots and realized she'd been shot and realized her daughter had been shot and ran inside for help, Rockdale County Sheriff's Office spokesperson Jodi Shupe said, the Rockdale Citizen reported.

Roberson turned himself in to police in Newton County a few hours later, the Rockdale Citizen reported.

He walked in and said 'I need to report a shooting. I just shot someone,' Shupe said, the Rockdale Citizen reported. We related him to our shooting, so we brought him over here. We are now questioning him and taken out the warrants.

The names of the woman and her daughter have not been released.

The woman was flown to the Atlanta Medical Center and her daughter was taken to Children's Healthcare at Egleston, the AP reported.

The mother was released from surgery in serious condition and her daughter was listed as being in critical condition, NBC's 11 Alive reported.

Roberson and the woman had been separated for approximately one year, and she filed for divorce on Monday, the station reported.
