i have no idea, sorry.
i haven't paid attention to the cosby family since mrs. cosby got tammy bruce fired from kfi am 640 in los angeles about 6 years ago.
all tammy did was say the obvious--that any person changing a tire in the dark on the 405 might be victimized by thugs, regardless of their skin color.
this angered mrs. cosby, whose son was murdered by a crazed russian immigrant. mrs. cosby said "america's a racist country". then she used her husband's name and billionaire status to get tammy fired.
But, money talks, and so Ms. Bruce unfortunately became a target in the gunsight of a mother who had no one to blame but fate and didn't want to accept that. The murderer was there and he just happened to kill her son rather than someone cosby didn't know or care about.
Stercus accidit.
