The only other person besides the Croslin/Cummings speaking out against cousin Joe is Grandma Flo. However, after listening to his tape of a phone call between Misty and Gma Flo on February 12,2010, I don't think Gma Flo can be considered "credible."

At the beginning of the call, Gma Flo tells Misty that she has an appointment with her psychiatrist later today. (I only mention this because Gma Flo does not seem like the type who would go.)
Starting about 3:13 in the audio:
Flo: What about all over the newspaper down there.
Misty: What? Whats on the newspaper?
Flo: Huh?
Misty: Whats on the newspaper?
Flo: Well according to your mama, day before yesterday, it was ah, that you had stated that Timmy, I mean Tommy and Joe did away with Haleigh.
Misty: That wasnt on the newspaper.
Flo: Huh?
Misty: That wasnt in no newspaper
Flo: She said the whole damn front page of the newspaper was covered with it.
Misty: Unh-huh, she's silly.
Flo: Yeah!
Misty: That wasnt on the newspaper.
Flo: Uh, thats what she told us..we got, uh
you know we got our private (something) investigators up here that's good on computers...and they're putting us on computer...and aint nobody done chit.
Misty: Well, cause, that wasnt on the paper.
Flo: Huh?
Misty: That wasnt on the paper. (giggle)
Flo: That wasnt in no damn paper.
Misty: Umph-huh, cause I keep every article that comes out.
Flo: Yeah!
Aunt: Why is her mama and daddy lying about it for? Come from her daddy.
Misty: I dont know.
Flo: She's like me...she don't know...just like I told her Mom last night this is all talk.
************
IMO, this call makes Gma Flo's credibility questionable and anything she says speculation/rumors. Gma Flo brings up the Tommy and Joe killing Haleigh two months before she went on National TV and told us Tommy confessed to her that Joe killed Haleigh. We know that Gma Flo gave Joe's name, not Tommy.
But Gma Flo in her own words is talking about getting info from people on computers. I can't make out the word between "private" and "investigator" but she states they are good on computers and they are going to get them on the computer.
Earlier in the audio, Gma Flo told Misty that they would be down there when she went to trial. They would have to sleep in their car but they would be there. On TV Gma Flo mentioned that she could not talk to Misty or Tommy because she did not have money for minutes. Obviously, when Gma Flo talks about having PI"s, she is not paying anyone.
IMO, Gma Flo has been repeating speculation, gossip and hearsay so we have no idea if anything she says is her own personal knowledge, something she was told directly by someone involved like Misty, Tommy, or Joe, or something she read/heard from computer sites. I don't think Gma Flo herself could separate what she knows from where she got the information.
IMO, I feel that anything Gma Flo says about Joe should be taken with a huge grain of salt unless we have proof that she witnessed it herself.
IMO, as Gma Flo jumped on the Joe killed Haleigh bandwagon two months before the media reported that Misty/Tommy said Joe did it, I believe Joe was always Plan B if Plan A - Haleigh abducted failed.
