There are grave concerns about the construction of Savannah State University’s new Science and Technology Center, literally. Last year when ground radar crews surveyed the parking lot between Kennedy and Drew-Griffith halls where the new science building is to be erected, they discovered three anomalies they believe to be graves containing the remains of three to five people. “The site is basically the parking lot area between Kennedy and Drew-Griffith,” said university spokeswoman Loretta Heyward.
