ST. PAUL, Minn. (AP) — A Minnesota jury has ended its second day of deliberations without a verdict in the trial of a police officer who fatally shot a black motorist.

Officer Jeronimo Yanez is charged with manslaughter in the July 6 death of Philando Castile. Yanez shot Castile seconds after Castile informed him he was carrying a handgun. He says Castile was ignoring his commands not to pull it out.

Prosecutors say Yanez overreacted.

Jurors returned to court briefly Tuesday morning to re-watch two key videos in the case. They'll resume deliberations Wednesday.

The mother of a black man fatally shot by a Minnesota police officer last July says her son shouldn't have died the way he did.

Valerie Castile, the mother of Philando Castile, posted a seven-minute video on Facebook. In it, she explains she's waiting for a jury to reach a verdict against St. Anthony police officer Jeronimo (yeh-RON'-ih-moh) Yanez, who shot her son during a traffic stop.

She says: "We need to just stand in solidarity."

Valerie Castile says she's praying for a guilty verdict, and that Yanez had time to decide if deadly force was necessary. She says Yanez didn't use his training to de-escalate the situation.

She says the killing of black men by police officers around the country needs to stop. She says, "This is no longer about Philando; this is about humanity."

Twelve jurors are in their second day of deliberations in the manslaughter case against Yanez.
