Hadden Irving Clark is an American murderer, currently serving two 30-year sentences for the murders of Michelle Dorr in 1986, whom he cannibalized, and Laura Houghteling in 1992. He was also given a 10-year sentence for robbery. He is the second of four children, and was born and raised in Troy, New York. Clark's brother, Bradfield Clark, strangled a woman in California; his father, Hadden, Sr., committed suicide. Clark confessed to the 1974 murder of an unidentified murder victim nicknamed "Lady of the Dunes" but many are in doubt due to his history of false statements.

Clark sent a letter claiming he had killed an unidentified woman on Cape Cod, Massachusetts in 1974. Clark explained that he had buried evidence from the crime in his grandfather's garden and that he knew the woman's identity but was not going to tell authorities because he claimed they mistreated him. Because he suffers from paranoid schizophrenia, police doubt this confession.
