A white former South Carolina police officer charged in the death of an unarmed black motorist is expected in court as his federal trial approaches.

A motions hearing is scheduled Friday in the case against 35-year-old Michael Slager.

Slager's federal civil rights trial in the death of 50-year-old Walter Scott starts next month. Another hearing is scheduled for Monday, when attorneys will discuss the admission of certain experts to testify.

Last month, a federal judge ruled prosecutors may show jurors video of the former North Charleston officer shooting Scott. The bystander's cellphone video was viewed millions of times around the world.

Slager also faces murder charges in state court, where his first trial ended in a hung jury. His retrial is scheduled for August.
