The Fall River Historical ­Society will mark the 120th anni­versary of the infamous Lizzie Borden murder mystery with an exhibit that will showcase new artifacts, as well as shed light on a part of her life never seen before.

The temporary exhibit, “Echoes of Lizzie,” is designed to tell the full story of the ­Borden family, and not just ­focus on the murders of Andrew and Abby Borden, Lizzie’s ­father and stepmother, who were found dead Aug. 4, 1892, with multiple lacerations from a hatchet.
