Welcome to WS, Winnow~
The only clips we saw of Melissa up until that point was her in the Kia and her in the backseat of the unmarked police car. I don't see him making the statement about those. I feel like there is something he was shown from LE (law enforcement) instead. Perhaps they were trying to illicit information on her past behavior from her father or family members by showing them her "confession" or parts of it. I could see LE doing this during questioning if they were adamant she could not have done anything to Sandra. (I would like to find out if there are other "films", too. It is suspected by other parents she was into child




according to the report from David Bergaud from KOVR on JVM.)
We don't know enough about her ex to say she was exposed to anything during that time, but those are stringent rules for visitation. Time will tell when we see where her daughter is placed now. I am still unclear on who she is with currently. (It was rumored she was with the "father and step mom", but not clear if it was her father or Melissa's father.)
