MYRTLE BEACH — The Horry County administrator has been instructed to investigate allegations against the county police department.

County Council Chairman Tom Rice says the investigation started before Horry County lawmakers asked the State Law Enforcement Division to look into allegations of misconduct by county police officers.

Rice says he expects a report Oct. 4.

Rep. Nelson Hardwick asked SLED Director Mark Keel last month to investigate allegations made in an anonymous letter sent to members of the county legislative delegation and Horry County Council.

SLED spokeswoman Kathryn Richardson says the request is under review.

Rice says most of the allegations are 10 years old.

The letter purports to be from an officer who cited misuse of equipment, confiscated drugs and money from the evidence room.
