An ex-convict charged with fatally shooting a Memphis police officer during a struggle is scheduled to appear in county court Wednesday.

Twenty-nine-year-old Tremaine Wilbourn is being held on $10 million bond on a first-degree murder charge in the Aug. 1 death of Officer Sean Bolton. It's not clear whether Wilbourn has an attorney to contact for comment on the case.

Wilbourn's sister, Callie Watkins, told The Associated Press last week that her brother told her during a phone conversation after the shooting that he was forcibly pulled out of a car by Bolton.

Police have said that Bolton approached the 2002 Mercedes Benz on foot after pulling up in his squad car and that he interrupted a drug deal.

Police say Wilbourn took out a gun and shot Bolton multiple times. Wilbourn was arrested after a two-day manhunt.
