Yes, the family is likely frustrated and confused and of course investigators can't give them any information so it only adds to their suspicions.
The interviewer is not helping much. She doesn't seem to know anything about the evidence LE talked about. She asked him, "They based it on a text message?"
LE never said that and they also never said they had a video of him deceased, or being deceased, or however they worded it.
Cody is surprised Marv is avoiding their phone calls. He basically answered his own question. He said Amber trusted him with King and knew him for a long time. He probably is consumed with guilt and likely knows what people are saying about him. If he does have a lawyer he has probably been advised not to talk to anybody about the case.
They keep talking about Tianna's cousin and how she apologized to the family and felt betrayed and it doesn't make sense. She said she wasn't feeling betrayed when she told police about the man with the gun. Of course she didn't, she believed the story at that point! She feels betrayed by Tianna and I don't blame her, especially if they were close. The interviewer implied she should be charged with giving the police false information. If she believed Tianna then she was just repeating what she told her. At least she admitted fault and is not denying the charges.
He also implied that police didn't care about King and simply gave up and they are just letting everyone think he's dead. Obviously that's not true if they had the FBI involved and utilized their behavior analysts, technical experts, and spent so much time viewing hours of cell phone and surveillance video, phone records and text messages.
I doubt there is any truth that King could still be alive. I've never heard of any missing persons case where police have notified family that a child is deceased, charged someone with murder and eight related charges, and then the child is found alive.
The family needs to be patient and wait until the investigation is over and the arrest affidavit and discovery are released. They also should stay away from social media. It seems to be filled with unknowledgable people who spread rumors and know nothing about how an investigation is run.
This is all just a distraction. The two sides bashing each other is not going to help anything. Police have said they are confident Tianna is responsible for Kings death and acted alone.
Perpetuating a rumor that he is still alive is not going to help the family. I hope they can stop listening to all these people. It's not going to help them get any closure. They need to be able to grieve in peace.
