The prosecution systematically built a pattern of OJ Simpson's controlling, possessive, and violent behavior toward Nicole Brown through testimony from neighbors, police, and her sister Denise Brown. Witnesses described surveillance incidents from 1992, a volatile 1993 domestic violence call, and increasingly graphic incidents of physical and emotional abuse spanning 1977-1993. The day also saw contentious discovery battles, including revelation of the prosecution's EDTA testing plans for socks to counter blood-planting allegations.
