(Reuters) - Pennsylvania prosecutors on Wednesday charged an East Pittsburgh police officer with homicide in the shooting death last week of an unarmed black teenager, the latest in a string of U.S. police killings of black men that has sparked nationwide protests.
Officer Michael Rosfeld, 30, surrendered to face a single criminal count for killing 17-year-old Antwon Rose on June 19 as the officer was searching for suspects after a drive-by shooting that wounded one. Authorities have not specified the type of homicide charge that Rosfeld will face.

Video of the incident, showing two men running from a car that was stopped by police and falling to the ground amid the sound of gunfire, sparked several nights of protests around Pittsburgh.
A series of police killings of black men in U.S. cities in recent years has fueled a national debate about racial bias in the criminal justice system.
Also on Wednesday, a white police officer in Kingsland, Georgia was arrested and will face voluntary manslaughter and other charges related to the June 21 fatal shooting of a black man fleeing after a traffic stop.
Zechariah Presley turned himself in and will face charges in the death of Tony Green, 33, the Georgia Bureau of Investigation said on Twitter.
Black clergy and the NAACP have held prayer vigils and protests since the shooting occurred, local media reported. Kingsland is about 35 miles north of Jacksonville, Florida.
Few of the officers who have faced charges for the killings have been convicted. U.S. laws give police broad powers to use deadly force when they believe their lives or the lives of others are in danger.
The fatal shooting in East Pittsburgh occurred after Rosfeld and other officers stopped a car while investigating the drive-by shooting. Prosecutors said Rosfeld first told them he saw a person emerge from the car with a "foreign object," but later admitted he did not see a weapon.
"An officer has to be in fear of death or serious bodily injury – then you can return that fear with deadly force," Allegheny County District Attorney Stephen Zappala told reporters. "Those elements are clearly not there."
A second passenger in the car with Rose, Zaijuan Hester, 17, was charged by Allegheny County police on Wednesday with several crimes in connection with the drive-by shooting, according to court documents.
Rose and the driver of the car were not involved in the drive-by shooting, Zappala said.
Rose, "in the last moments of his life, did something critically important – he showed his hands," he added.
Rose's family viewed the charging of Rosfeld with "guarded optimism," said their attorney, Lee Merritt.
"We realize that conviction is a long road ahead," Merritt told Pittsburgh's WTAE-TV.
Rosfeld's attorney, Patrick Thomassey, told Pittsburgh's WPXI television that the officer had turned himself in early Wednesday and was released on an unsecured bond of $250,000.
Michael Slager, a former officer in North Charleston, South Carolina, was sentenced in December to 20 years in prison for shooting an unarmed black man following a traffic stop.
