LOUISVILLE (WHAS11) -- A Louisville mother is dead, three others are in the hospital and even more families without a home following a fire at a Lake Dreamland apartment building. Arson investigators are calling it an on-going criminal investigation due to the circumstances.

The victim has been identified as 41-year-old Archimeda Riley.

As flames devoured the building, neighbors said Riley worked tirelessly to save her children.

"She put the baby out the window and was telling my girlfriend please grab my baby, please save my baby and then the window shut and that was the last thing we heard from them," Idallas Moore, who lives in the building, said.

Fighting for her family, Riley pushed one of her children out of the window, into the arms of neighbors.

Four other children were also thrown out apartment window to escape the flames. Neighbors said the oldest child was eight and the youngest was a newborn.

"We didn't care about what the risk was. We was just trying to get safe, we was just trying to get out and get safe," Moore said.

Neighbors said Riley and two other children were still trapped in the apartment with no way out. The hallways were consumed in flames and smoke was leaking into every room.

Moore said, "It was just going to be bad. I could tell. Like the flames went right up."

When rescuers got on scene they rushed into the burning building to find Riley and her children.

"It was like something you see in a movie, you would never expect it to happen. But it was real. It was real," Moore said.

Four people left with EMS.

Riley died at the hospital.

"I just want justice. I was justice for Miss Archi because I swear she is sweet lady and she did not deserve any of this. We need justice for Miss Archi and her family," Moore said.

The cause of the fire is still unknow. Arson investigators are working the case.
