yeah, i think there were varying reports of that that i've never seen confirmed.
i believe misty's brother has 3 little kids (one a baby maybe), and he lives right around the corner (assuming he is THE brother).
it was supposedly ron's gma that dropped off the clothes and possibly ron's mom in the driveway that drove the gma to ron's house. misty never mentioned them coming over in her tv interviews, though. and first ron's mom said she had relatives over there that night, and then i think she said that she drove gma over there (which would mean she was there, too). to me, it sounds like a suspicious story and she could be trying to provide an alibi for ron and/or misty. or it could be completely true......
