A friend of the man accused of gunning down nine black parishioners during a Bible study in a South Carolina church wants to delay his own sentencing.

Joey Meek has pleaded guilty to lying to authorities and failing to report a crime regarding what he knew about Dylann Roof's violent plot.

An attorney for the 21-year-old requested the motion for delaying the sentence to be filed under seal, citing Meek's "medical issues."

Meek faces a possible prison sentence of eight years, though prosecutors say they'll argue for a shorter sentence if he's cooperative in their case against Roof.

At his plea hearing, Meek's attorney said her client had sought psychiatric treatment. As part of her delay motion, attorney Debbie Barbier said she plans to file a letter from a psychiatrist.
