In an exclusive interview, Nelson told Eyewitness News her side, saying, "I'm not a monster. I have five grandkids and I love kids." Family members say the charges are surprising, but police have a much different opinion.
"(I) don't believe at all she has anything to do with killing a child," said Nelson's sister, Angie Johnson. "That's not Mona."
"She Is a cold soul-less murderer," said HPD Homicide Detective Mike Miller.
Foster's charred remains were found in a ditch earlier this week. Detectives say evidence at Nelson's house linked her to the murder.
