Memphis Cop Killing Suspect Surrenders

The emotional manhunt for a paroled bank robber suspected of fatally shooting a Memphis police officer ended Monday evening when the suspect surrendered to the U.S. Marshal's office, local and federal authorities announced.

Tremain Wilbourn, 29, was accompanied by his family when he arrived at the federal building in Memphis, the U.S. attorney's office said shortly after the Shelby, Tenn., sheriff tweeted that he was in custody, reports USA Today .

Wilbourn is accused of killing Officer Sean Bolton, 33, during what started out as a simple traffic stop Saturday night, Armstrong had said. Bolton had stopped to examine a vehicle parked illegally in a South Memphis neighborhood but apparently interrupted a drug deal. Wilbourn was in the passenger seat and, after "some type of physical altercation," he drew a gun and shot Bolton, Memphis Police Director Toney Armstrong said.

Wilbourn had been free on supervised release for a 122-month bank robbery sentence, Armstrong said. Wilbourn now faces a first-degree murder charge. He is due in court Tuesday.

Armstrong said the drug transaction in question amounted to "less than two grams of marijuana," which constituted "a misdemeanor citation and a fine."
