The Medford Public Library is co-sponsoring an online program with true crime writer E.C. Hanson, who will speak about his latest book, “Dead End Road.” In June 1977, Renee Freer, nicknamed Giggles, went out to play with her friends. A few hours later, she was found bludgeoned to death with a rock. In a true crime book unlike most, E.C. Hanson stumbles upon an unsolved murder case that haunted his former stepfather. Unable to get specifics from the old and new guard of detectives, Hanson forges ahead, mining what he can from previously released articles and people who lived in the neighborhood at the time. An unusual yet passionate text, “Dead End Road” honors Renee Freer’s memory and asks how will you help? Register for the Zoom program using the link on the library’s online calendar.
