Strozier admitted to investigators that she delivered an envelope to the inmate — a "serious violation" of rules — but said she was unaware of the contents, Jones said.
Strozier was dismissed, after nearly four years with the Sheriff's office.
Antonio Hill, 36 and unrelated to the inmate, was fired for admittedly allowing Crossley to bring clothes to inmate Hill. Officer Hill also failed to document Crossley's visits to the inmate, authorities said.
Everett Hill, 28, has a lengthy criminal history with drug and weapons arrests in DeKalb dating back to 1998 among his offenses, jail records show.
He most recently was booked into the jail in November on burglary, aggravated assault, witness tampering and weapons charges, according to jail records.
