That is Ron's stock answer for everything and IMO it carries little weight as LE is still saying they don't know what the crime is or *when* the crime was committed. LE is basically stating they don't at this time find Ron's "I was at work" a valid alibi but Ron keeps thrusting it out every time someone asks him a hard question.
He gave his alibi (I was at work) FIRST to 911 before informing them his daughter was missing and asking them to help.
Misty did the same thing (I was sleeping and I woke and got up...) rather than crying out for help first and foremost.
I called 911 once when my grandma fell down the stairs and I was hysterical...all I could say FIRST was please send the paramedics because my grandma is hurt. I didn't start by saying I wasn't near the stairs and didn't know what happened. When someone calls 911 and gives their alibi FIRST it is a red flag to LE. I've seen this stated on shows like Forensic Files.
911 kept me on the phone and tried to calm me down. I did not swear at them and tell them I didn't have to answer their questions nor did I hang up on them even though I was eager to get back to my grandma. I found the hang ups and swearing to 911 on Ron's part to be very hinky from the get go.
Also, Misty identifies herself TWICE as Haleigh's mother. Ron does not correct 911 when they identify Misty as his wife. 911 needs the correct information in order to help LE and those responses were misleading info for LE. They were also easily set straight to 911. Sure those two could have been upset but so upset that they didn't know who they were to Haleigh and each other? I'm not buying that.
As for his posture on the Today show. What caught my eye first was that not only was he not touching Misty (no arm around her shoulder or hand holding) but while she was sitting upright and close to him, Ron was leaning slightly *away* from Misty almost as though he was distancing himself from her. Every picture tells a story.
ITA: When I first heard it I thought it sounded like overkill. I don't know.
