Franklin B. Evans (1807 – February 17, 1874), known as The Northwood Murderer, was a 19th-century American murderer and suspected serial killer. He was convicted for the brutal murder of his niece Georgianna Lovering in Northwood, New Hampshire, in 1872, and later confessed to another similar murder in Derry, committed in 1850. He was suspected in at least three other child murders in Maine and Massachusetts, but denied responsibility for them. He was executed at the New Hampshire State Prison for Men in 1874.
