Police are still looking for possible links in a rash of fires near downtown Columbia, including one that killed an 80-year-old woman last month.
The agency is also investigating two fires that broke out early Feb. 2 in vacant homes in the MLK Park neighborhood. A police spokeswoman said Wednesday that the two homes did not have electricity at the time of the fires.
The State Law Enforcement Division is assisting with the investigations.
Police continue to follow up on tips received through the Crimestoppers hotline and encourage anyone with information to call 1-888-CRIME-SC. Callers could receive a cash reward of up to $1,000.
