The father of Nicole Brown Simpson died Thursday after battling a lengthy illness, his family announced Friday. Louis Brown Jr., 90, whose ex-son-in-law O.J. Simpson was accused of murdering Nicole Brown Simpson in 1994, died with his family at his side, a family spokeswoman said in a statement.

O.J. Simpson, 66, currently in prison on a 2008 robbery conviction, was acquitted of his wife’s murder in 1995 after a closely-followed trial. Louis Brown would go on to form the Nicole Brown Charitable Foundation after his daughter’s death, which is an organization that helps victims of domestic violence.
