TMZ has posted pictures of Mama June and Mark appearing to be house hunting together in Georgia last month, which has raised questions about her children's well-being.
"I firmly expect Department of Family and Children Services to investigate whether this is still a safe home for Honey Boo Boo and her siblings," Nancy Grace told ET. As of now, Georgia's Department of Family and Children's Services cannot comment on any case including this one.
"My main concern is the safety of Honey Boo Boo and her three siblings that are still in the home," said Nancy Grace. "When I heard that he's in the home, I nearly did a back flip."
Mama June's oldest daughter Anna "Chickadee" Shannon, now 20, is speaking out, telling People that she was molested by McDaniel when she was eight years old. She says that McDaniel "would try and touch [her] and all that stuff."
This isn't the first time the family has come under fire. Mama June -- who has four daughters: Alana "Honey Boo Boo" Thompson, Lauryn "Pumpkin" Shannon, Jessica "Chubbs" Shannon and Anna "Chickadee" Shannon -- was investigated by Child Protective authorities in 2012 when Honey Boo Boo was seen on Toddlers & Tiaras drinking "go-go juice" -- a blend of Mountain Dew and Red Bull -- but no charges were ever filed.
While she's facing public scrutiny for this current saga, Mama June has been prudent with her children's money, putting their earnings in a trust fund.
TLC canceled Here Comes Honey Boo Boo after the report that Mama June was spending time with McDaniel.
"TLC has cancelled the series Here Comes Honey Boo Boo and ended all activities around the series, effective immediately," the cable network said in a statement. "Supporting the health and welfare of these remarkable children is our only priority. TLC is faithfully committed to the children's ongoing comfort and well-being."
Mama June responded to the cancelation via Facebook post, writing, "It isn't true. I promise my kids r #1 priority over anything else and I would never put them in danger, period, over this or anything else. They r my life. This is my past. I left him 10 yrs ago for it and I wouldn't go back."
