Wednesday, December 29, the day after Hailey was reported missing was the first time Billie's house was searched.
LE stated that Hailey's home had been searched 3 times by January 6. After the initial search, the Texas Rangers searched it IIRC January 3 or 4, and then LE searched again when they executed the search warrants. That would be the 3 times (initial, Texas Rangers, search warrant).
IIRC the search warrants were served on January 6, and that's the only date I know of that it's been reported in MSM that Shawn's mother's home was searched.
I don't recall seeing anything in MSM about Shawn's grandmother's home being searched.
I haven't had my second cup yet, so didn't pull the links. If anybody wants them, holler and I'll get them.
