A man suspected of killing a police officer during a traffic stop in Tennessee turned himself in Monday, officials said, following a three-day manhunt.
Memphis police officer Sean Bolton, 33, was shot several times on Saturday when he approached a car that was apparently illegally parked.
Bolton was rushed to a hospital in critical condition and later died of his injuries.
Police launched a search for suspect Tremaine Wilbourn, whom they said was armed and dangerous. Authorities had offered a $20,000 reward for his capture.
Wilbourn turned himself in Monday, according to the Shelby County Sheriff's Office.
"Wilbourn is in custody! He surrendered to the US Marshal's Office," it said in a Facebook post.
"Now we hope Officer Bolton can truly rest, that his family can begin to grieve, and that as a community we can all begin to heal," it added.
Shelby County Sheriff Bill Oldham offered his condolences to the slain officer's family.
"Great job to all involved in putting the pressure on," he said in a statement.
"I will continue to pray for Officer Bolton's family, and all of his extended family."
Bolton had been with the Memphis Police Department (MPD) since October 2010.
The shooting came just days after a white Ohio policeman who shot a black man during a traffic stop pleaded not guilty to murder charges, the latest in a string of incidents that have heightened racial tensions in the United States, particularly in relations between police and black Americans.
