Murder of Hannah and John E. Peck

Hannah and John Edward Peck were an American married couple that were poisoned with arsenic by their son-in-law Arthur Warren Waite in 1916.

The murders
Arthur Warren Waite married Clara Louise Peck, the daughter of Hannah M. Peck (née Carpenter) and John Edward Peck on September 9, 1915, in Grand Rapids, Michigan. Hannah Peck was poisoned with arsenic and died on January 30, 1916, at the home of Waite and his wife and the victim's daughter Clara Peck. John Peck travelled from Grand Rapids, Michigan to Manhattan, New York City and he died on March 21, 1916. Waite poisoned him during a dental exam and gave him additional arsenic in his food. When the death was too slow he gave him ether and smothered him with a pillow.

Waite was found guilty and sentenced to death via electrocution at Sing Sing on May 24, 1917.
