The Latest on the killing of a black man by white Louisiana police officers (all times local):

8:45 a.m.

The 15-year-old son of a black man shot and killed by white Louisiana police officers says his father, Alton Sterling, was "a good man" and called for people to come together to deal with violence.

Cameron Sterling said during a news conference Wednesday that people should protest but that they protest peacefully.

Just a week earlier, the teenager had broken down in sobs as his mother talked about his father's death and had to be led away from those gathered at a news conference.

On Wednesday, he appeared before microphones calm as he asked people to remember his father and to make sure that something positive, and peaceful, resulted from what he called his father's sacrifice. He called for people from all races to unite as one as they remember Sterling.

BATON ROUGE, La. (AP) — Police say they've arrested three suspects accused of stealing several handguns as part of an alleged plot to harm police officers in the Baton Rouge area.

Baton Rouge police Chief Carl Dabadie said at a news conference Tuesday that authorities discovered the plot while responding to a burglary at a pawn shop. They arrested one suspect on the scene and then tracked down two others. Authorities called on the fourth suspect to turn himself in.

State Police Col. Mike Edmonson called it a "substantial credible threat" to police.

The arrests come after the deadly police shooting of a black man by two white police officers in the city and the killing of five police officers in Dallas last week.
