Seeking name of Police Officers for West Southern Pines, NC

The chartered township of West Southern Pines, NC was run by negros (blacks) in the 1925 - 1929 era. The town had a negro mayor and council.  The police officers were also negros and one was my grand father (Frank Waddell).  Where might I find minutes of the council or police department records for the township.  The west side was annex to the east side to become the township in Southern Pines, NC around /about 1930.  Any information or guidance you can share on the West Southern Pines, NC era would be great.
