UPDATE: South Pittsburg's police chief, Bobby Simpson, said the medical examiner looking into the death of a toddler will be ruling it a homicide. While the TBI isn't ready to call it that, Channel 3 spoke with the parents of 2-year-old Zayne Harper.

Right now, no one has been charged.

"It's my baby. He's gone and he's not coming back," Essence Robinson, the child's mother said.

Robinson's son just turned two last week. His sudden death has taken an emotional toll on the young mother.

"He was such a good baby. He loved to be around other kids. He loved to play. He loved to be outside. He loved swimming," Robinson said.

The TBI said the child died at a Chattanooga hospital on Friday. The agency is looking into the case along with the South Pittsburg Police Department and the Marion County Sheriff's Office.

"All I know is, whenever I got to the hospital, I watched my child die 3 times. I was sitting there watching them bring him back to life and it looked like he was beaten. My baby never looked like that. He was happy. He was a happy child," Eddie Harper, the child's father said.

He and Robinson haven't been together since the toddler was three months old.

"I want to know what happened to my baby. I want to know why my baby had to go. My baby wasn't nothing but an innocent soul," Harper said.

Chief Bobby Simpson said the child suffered from extensive injuries, but couldn't elaborate.

"We know that the child was in the care of an individual and at some point the child became unconscious. They went to the hospital," Chief Bobby Simpson of the South Pittsburg Police Department said.

Simpson said Robinson's boyfriend was taking care of her son.

Channel 3 spoke with the boyfriend's birth mother since he's under 18. She said two-year-old Zayne was riding a bike when her son and the little boy collided on Thursday.

Her son didn't notice something was wrong until the next day and that's when she took them to the hospital, according to the boyfriend's birth mother.

Both parents are now organizing funeral arrangements.

"I'll never get to see my son again. I'll never get to touch him. I'll never get to hold him again. I'll never get to watch him play no more," Harper said.

"I know he's with God now and is looking over me right now. I know he's an angel right now," Robinson said.

The TBI said along with the autopsy, agents are collecting evidence and conducting interviews as part of the investigation.
