This is her theory and hypothesis of how Anna was killed.

There were reportedly bruises on the side of Anna's neck.

And a bar hold, if you're unfamiliar, is when someone

wraps and holds your neck in the crook of their elbow.

Anna's grandparents are stating that she was not found beaten.

There were bruises on her neck from the asphyxiation, but it's not like Martin Donoghue's ex-post where it says that she was beaten up, there was evidence of essay and all of these other things.

Anna's family is refuting that.

They're saying, actually, no, there was no signs of drugs or alcohol in her system.

There was no signs of essay, but yes, she was killed, basically.

The death certificate does not show, but this is not her autopsy.

Anna's grandparents, who she's been really close with, I mean, they might have been some of Anna's favorite people in the entire world and more on that later, but they do an interview with ABC, like I said, days after Martin Donahue's social media post.

And the grandma says she was found concealed under the bed.

I was told that the room attendant pulled back the mattress and found Anna.

The FBI contacted my son, Chris Kepner, and told us her cause of death was asphyxiation.

They said when they took her body to the medical examiner's office, it was in perfect condition.

Anna's grandparents further tell ABC News that there were no signs of SA, drugs, or alcohol.

And as for the social media conversation of the stepbrother, the 16-year-old stepbrother being the suspect, Anna's grandparents say, I mean, he was in the room with her.

He was the only one seen coming and going.

So I can't accuse him because I don't know what happened in that room.

But the summation would be that he did something.
