Mariah's mother Kristy Woods reported of her child's disappearance early last week. Mariah's body was found December 2.
The court documents accuse Earl Kimrey of sexually abusing Mariah and hitting the two boys with a belt - one of them in the face, causing a nosebleed.
State records show Kimrey had previously been charged with a series of lower-level crimes dating to 2005. The Onslow County Sheriff's Office says Kimrey is being held on more than $1 million bond in the Onslow County Detention Center on charges that include concealing a death and obstruction of justice. "I will be awaiting the results of the medical examiner's report and making some decisions at that time".
The teddy bears at the memorial will go to Mariah's two brothers while all toys that remain will be donated to children in the Department of Social Services and to first responders.
The public is welcome at the vigil, scheduled for 7 p.m.at Dawson Cabin and Ernest King roads in Onslow County. He attended Orange County High School in Hillsborough and Alamance Community College, according to the Facebook page.
"I'll do anything that I can, whatever you want", said Woods, according to WNCN.
As the memorial grew, many in the community were still searching for answers in Mariah's death.
A medical examiner has not yet confirmed the person's identity, she said. I called the aunt yesterday and they were in tears. "And this morning she asked me if she could make her a little card and asked if she could say "hi" to God for her". "Something so tragic has impacted our own children that are still here with us".
"We put every resource we have into finding Mariah, to bring her home safely", he told reporters.
As investigators continue to gather evidence in the case, people in the community are leaning on one another for support.
"I really and truly think that we feel that we let her down", said Purdy.
"We drive by the house everyday to take her to preschool, pick her up from preschool", said Tiana Purdy who had to explain the entire story of the search and recovery to her daughter.
An FBI spokesperson said Sunday that the case is now a state homicide investigation and the agency will no longer be involved.
