I am wondering if MB and CB didn't move to MO and left the kids with KB until they were settled so they got custody in CA so they could take care of the kids. Maybe that time it was a volunteer situation rather than because social services stepped in. The MB and CB kept getting into trouble in MO and the kids were going to get put into foster care so KB, GB and AuntKNP came to the rescue.
I am guessing something like that happened, as KB seems to chasing MB around cleaning up in her wake --but
1994 MB has AB with CB*
1998 MB has twin boys with CB*
2002 GM sought guardianship in in CA (NT article)
2002 CB by then had moved to MO as he was charged with assault(Casenet) (rumor is stabbing)
2002 MB has address and phone number records in MO
2003 AB's half sister born --
2004 GB and KB still in CA (property records, and other collaborating accounts)
2005 Lomo property purchased (property records)
2005 MB's record for traffic trouble started (seatbelt violation Casenet) and this was after the gps moved to MO as Lomo address is on court document (Casenet)
2005 GM files in MO for custody (Casenet -- removed or hidden since end of October)
2007 GM files in MO for custody of AB's half sister (bio father listed as respondant)
a few things bother me about this timeline
1 - why would MB just start getting in trouble AFTER her mother moves to MO? (no record IMO may mean she was not in MO before 2005) the bio father had been in trouble 3 years before they moved?
2 - why would there not be a record for MB regarding kids being taken away?
3 - when did the kids move to MO for the gps have to come to their rescue ?(they already had guardianship in CA 2002, and they filed for it in MO in 2005)
I am willing to bet the bio parents did not all of a sudden start getting into trouble --the first of their trouble happened in 1994 --perhaps something happened in CA that caused at least CB to move**, and the gps gain custody in CA
* suggested adds to the timeline from Gliving --(thanks!)
** at least CB and MB were in MO in 2002
