The shooting deaths of two black men within days by law enforcement officers are the latest in a spate of such cases that have made headlines nationwide in recent months.
A Minnesota officer fatally shot a man — identified by relatives as 32-year-old Philando Castile — while he was in a car with a woman and a child in Falcon Heights, a St. Paul suburb. The aftermath of the Wednesday shooting was purportedly livestreamed in a widely shared Facebook video, which shows a woman in a vehicle with a man whose shirt appears to be soaked in blood telling the camera "police just shot my boyfriend for no apparent reason."
A day earlier, 37-year-old Alton Sterling was shot and killed during a confrontation with two police officers outside a Baton Rouge, Louisiana, convenience store where he was selling music and movies on discs. Cellphone video of the shooting posted online by a community activist set off angry protests.
Here's a look at other recent cases involving law enforcement officers:
Michael Slager faces up to 30 years in prison if convicted of murder in the shooting death of Walter Scott, who was shot and killed running from a traffic stop in North Charleston, South Carolina, in April 2015. Scott was unarmed. The shooting was captured on cellphone video by a man passing by and reignited the debate over how blacks are treated by law enforcement officers. Slager, 34, who is white, was fired by the North Charleston Police Department and stands trial in October.
Twelve-year-old Tamir Rice was shot by police in less than two seconds outside of a Cleveland recreation center in November 2014. Two officers had arrived at the scene in response to a 911 call about a person with a possible gun. Rice had a toy pullet gun and appeared to be reaching inside of his waistband when he was shot, the officers said. A grand jury in December declined to indict Timothy Loehmann, the officer who fired the fatal shot. In April, the city of Cleveland settled a $6 million civil rights lawsuit brought by the boy's family.
In 2013, Jonathan Ferrell, a former defensive back for Florida A&M University, was in a car accident in North Carolina late at night, and knocked on doors looking for help. Charlotte-Mecklenburg police arrived after responding to reports of a possible burglar. Ferrell was fatally shot amid the confusion, and a voluntary manslaughter charge was brought against Officer Randall Kerrick. A judge last August declared a mistrial, and prosecutors said they wouldn't seek a retrial. Charlotte-Mecklenburg agreed to pay Kerrick $113,000 and an additional $16,000 for Social Security and retirement as part of a settlement with him.
Chicago Police Officer Jason Van Dyke is charged with first-degree murder in the 2014 shooting death of black teenager Laquan McDonald. Van Dyke was charged in November on the same day that the city, on the orders of a judge, released the explosive dash cam video showing the 17-year-old McDonald being shot 16 times. Van Dyke has pleaded not guilty and is free on bond. The video has prompted local and federal investigations of both the shooting and the police department.
Ray Tensing, a former University of Cincinnati police officer, is awaiting an October trial on murder and voluntary manslaughter charges in the fatal shooting of Samuel DuBose, who was unarmed when he was pulled over for a traffic stop. Tensing pulled over DuBose last July near campus for a missing license plate. Tensing's attorney has said the former officer feared being dragged under the car as DuBose, 43, tried to drive away. Tensing, who is white, is free on $1 million bond. DuBose was black.
Peter Liang, a rookie New York City police officer, was convicted Feb. 11 of manslaughter in the death of 28-year-old Akai Gurley. Liang was patrolling a public housing high-rise with his gun drawn in 2014 when he fired and a bullet ricocheted off a wall, hitting Gurley, who was black. Liang, an American of Chinese descent, said he had been holding his weapon safely when a sound jarred him and he accidentally fired. In April, a judge reduced the conviction to negligent homicide and sentenced Liang to five years' probation and 800 hours of community service.
The November shooting death of 24-year-old Jamar Clark sparked weeks of protests in Minneapolis. Authorities say Clark was killed during a struggle with police. The officers, Mark Ringgenberg and Dustin Schwarze, were trying to arrest Clark when he was shot once in the head Nov. 15. He died a day later. A key issue in the investigations was whether Clark was handcuffed when he was shot. The federal and state probes came to the same conclusion: Clark was not.
A North Carolina prosecutor concluded that a white officer acted in self-defense when he shot a black man in Raleigh. Police have said 24-year-old Akiel Denkins pulled out a gun and reached for Officer D.C. Twiddy's weapon before the officer shot and killed him in late February. Twiddy was trying to arrest Denkins after he failed to appear in court on felony charges related to selling cocaine.
