Jeffrey Lynn Hand (February 2, 1949 – January 24, 1978) was an American murderer, kidnapper and suspected serial killer linked to two known murders committed in Indiana from 1972 to 1973. Deemed mentally unfit to stand trial for the latter, he was released and later killed following a botched kidnapping attempt in 1978. He was posthumously linked to the 1972 murder via DNA profiling, and authorities are currently investigating his possible involvement in other cases.
