MERIWETHER COUNTY, GA (WTVM) -- Casey Spradlin, 25, sits behind bars in Meriwether County charged with the murder of his girlfriend's son.
It all started nearly two weeks ago when 911 got a call to their home in Luthersville about a child that had fallen and was not breathing.
Few details are being released as to what happened inside the house but GBI agents say when paramedics got here, they found 2-year-old Brayden Robinson unresponsive.
He was air lifted to Egleston Children's Hospital in Atlanta. That's where agents say his injuries raised some red flags.
"During the medical evaluation of the child, treating physicians noticed bruising and injuries on the child which were not consistent with a fall or they were suspicious," revealed GBI Special Agent in Charge Rodney Wall.
Meriwether County Sheriff Steve Whitlock says at that point, his department and the GBI started investigating the case.
Several days later, little Brayden Robinson passed away.
According to agents, new autopsy results show Brayden died from blunt force head trauma not associated with a fall, as Spradlin had initially told authorities.
Agent Wall says Spradlin, a firefighter in Coweta County currently on military leave from the Georgia National Guard, was Brayden's sole caretaker at the time the trauma was inflicted that caused his death.
Spradlin turned himself in Tuesday and faces charges of felony murder, malice murder, cruelty to children and aggravated battery.
"This is really awful for the community and really anywhere because it's a small baby like this. He had his whole life to look forward to. It's a real bad situation," Sheriff Whitlock told News Leader 9.
Casey Spradlin is being held in the Meriwether County Jail.
