In that news report, her father says a few things. It ends with him saying, "The future is more interesting. It's better for us. You can't live in the past."
Purely my current opinion: The entire family has struggled greatly and there wasn't an ideal place for Rio to be living, because she was surrounded by instability and negative influences. (I don't mean any offense to her family but think she wasn't spending time with a good crowd of "friends" when living in either home. Her mother says this in the Podcast.)
Her father's words strike me as complete denial, by someone who is unable to handle the full gravity of what's happened and is trying to skip all of the pain and speed through the mourning process. He is focused on himself and not Rio, because that's what he's capable of right now.
IMO it's still unclear whether she was abducted there, not far from her father's home. I hope LE have looked closely at all possibilities, searched vehicles, asked for cell phones, etc.
A friend on the news report said she thinks many people know more but won't go to police. Hopefully people will anonymously send what they know to the police.
