The ex-con accused of killing a Memphis police officer has turned himself into federal authorities, ending an intensive two-day manhunt.
Louis Goggans, spokesman for the United States attorney's office in Memphis, said Tremaine Wilbourn turned himself over at the federal building. His family was with him when he arrived.
A warrant was issued Sunday for his arrest on a charge of first-degree murder.
