The Stanislaus County Sheriff's Department is expected to conclude its investigation into an officer-involved shooting later this week, about the time a rally will be held condemning "police brutality" in the Central Valley.
On Friday, off-duty sheriff's detective Kari Abbey shot and killed 31-year-old Rita Elias after what neighbors say was an hourlong argument outside an apartment complex on the 1700 block of Donald Street.
Stanislaus County sheriff's spokesman Andrew Winters said only that Abbey was in the area for "personal business." He would not say what the women were arguing about or if they knew each other before Friday.
Sheriff's officials said there is evidence Elias brandished a gun during the confrontation, which prompted Abbey to draw her concealed weapon. Every officer is given a permit to carry a concealed weapon off-duty but is not required to do so.
Winters said Abbey fired multiple shots but would not specify how many.
Friday's incident marks the seventh officer-involved shooting in the Modesto area since December.
An organization known as the Central Valley Coalition Against Police Brutality has organized a rally for Thursday. The group will gather at 6 p.m. at Paradise Avenue and Martin Luther King Drive to protest what member James Henderson describes as "rampant police brutality."
"We want people to know they don't have to be afraid in calling an end to police violence," Henderson said.
The coalition is part of a larger organization that was formed in response to the shooting of Oscar Grant by a BART officer in Oakland in 2009.
