Court records show a suspect has been officially charged in the fatal shooting of a Memphis police officer.

Shelby County court records posted online show 29-year-old Tremaine Wilbourn is being held on $9 million bond. Authorities say Wilbourn turned himself in Monday after arrest warrants were issued for him in the shooting of 33-year-old officer Sean Bolton on Saturday night.
