He was found three hours later by Bill Lewis, Blackwell"s father-in-law and the little boy"s grandfather.
According to WSOC, the coroner declared the cause of death "hypothermia with asphyxiation due to being in a refrigerator."
The incident occurred on February 27th, and it the investigation went on for six months before authorities arrested Blackwell, 27.
"This case was under heavy investigation," count coroner Terry Tinker told told the news station.
"Initially, we did not know why the body was so cold."
First responders performed CPR on the newborn,and were able to get a faint heartbeat, according to the incident report. They also did their best to bring up his body temperature, but doctors were unable to save him.
Tinker said that lengthy investigations like this do take as long as they do, since several people had to be interviewed.
"There were ten people at the home when the child died," Tinker confirmed.
"Investigators had to speak to everyone who was there."
Lewis is convinced his daughter-in-law is innocent.
"She didn"t do it. We don"t know who did," Lewis told reporters from his front porch.
"We just know she didn"t do it because she loves her kids too much."
Lewis spoke briefly to WSOC about his late grandson, getting emotional about their last time together.
"I held him for two and a half hours," Lewis recalled as he choked up.
"And I sang to him, and talked to him, and that was the only time I did."
The baby had a 2-year-old brother who is now in the custody of the Department of Social Services.
The family believes that Blackwell has a mental disability, but they also mentioned that a ten-year-old with autism may have put the child in the fridge.
Blackwell is being charged with felony homicide and child abuse, and could face up to twenty years in prison.
