PLATTE COUNTY, Mo. -- Details continue to emerge in the fire near Edgerton, Mo. that killed four people and is now being investigated as a homicide.
FOX 4's Megan Dillard spoke with family members of the victims. Shelly Denham lost her daughter, Heather, and her 3-month-old grandson, Mason.
"It's just been a roller coast of emotions. My worst nightmare came true, losing my daughter and a grandson," Shelly said.
Denham said little Mason was the light of her daughter's life.
"Ever since she had him, she's been the happiest I think she's ever been in her whole life," Shelly recalled. Now she clings to the items she has left that hold special importance to her daughter's memory.
She holds close Heather's slippers and wears a bracelet and pink jacket, both simple, yet meaningful gifts.
"It has "God" on it. So I've been wearing this and I keep hanging on to God because that's all I've got, is my faith. I don't have my little girl anymore. I don't have my little grandson. And I don't know where my son is," Shelly said.
Her son, Grayden, has been missing since the fire and on Sunday was named by police as a person of interest in the investigation. The family hasn't heard from him and police want to question him.
"We don't know where Grayden is, and we don't know if he's alive or not, and we want to find him," Shelly's brother, Kevin Shelton, said.
The family put out a plea to Grayden in the hopes that it will bring some answers.
"I love you very much and..." Shelly said fighting through tears.
"Just call. Call. Call as soon as you can," Kevin said.
Shelly said the other two victims are her former in-laws, Heather and Grayden's grandparents.
Mount Zion Baptist Church, where Shelly said Heather and Grayden's grandparents attended, are holding a vigil Sunday night.
A GoFundMe page has been set up for anyone who would like to help the family with funeral costs.
UPDATE: The Metro Squad said in a news release Sunday evening that Grayden had been located by authorities.
