The gunman suspected of killing a Memphis police officer on Saturday now is in custody, following a two-day manhunt for his capture in Tennessee.

Tremaine Wilbourn, 29, turned himself in to the U.S. Marshals Service office on Monday just before 5 p.m. local time. He faces first-degree murder charges for allegedly fatally shooting Officer Sean Bolton multiple times during a traffic stop on Saturday night in Memphis.

"You have to understand this has been an exhaustive search, both physically and mentally," Memphis Police Director Toney Armstrong told reporters on Monday night. "I think he felt the walls closing in and thought it would be in his best interest just to turn himself in."

Investigators said Bolton's traffic stop interrupted a drug deal between Wilbourn and the driver of the vehicle, who later turned himself in and was released without charge. Digital scales and less than 2 grams of marijuana were found inside the vehicle.

Wilbourn was booked into the city's Shelby County Jail on Monday night. His bond is set at $9 million. He had been on supervised release after serving a federal sentence for armed robbery.

The Memphis Police Association has established an online fundraiser to assist Bolton's family with his burial expenses.

Tremaine Wilbourn was booked into the Shelby County Jail last night on the charge of First Degree Murder. His bond is currently set at $9,000,000.00.
