A plea agreement signed by federal prosecutors shows that 21-year-old Joey Meek has agreed to plead guilty to lying to authorities and failure to report a crime.
Authorities have said Meek failed to tell investigators all he knew about the plans of Dylann Roof (above) to shoot nine black parishioners at Emanuel AME Church in Charleston, South Carolina, last June.
Roof is charged with nine counts of murder in state court and with hate crimes and other charges in federal court.
Meek had been set to go on trial later this year.
The agreement did not give a date for his plea hearing.
