Long was born on September 21, 1905, in Hartford, Connecticut. He was an only child born to Sarah Long, and he came from a rich family. Long later moved to Belmont, Massachusetts, where he committed his first crime. In 1924, he attacked a little girl and assaulted her. The girl managed to bite Long during the attack and Long fled. She survived the attack and was found by a Belmont police officer. The bite mark helped convict Long, and he was sent to a Massachusettsreformatory. He was paroled, however. In July 1930, Long attacked his second victim. He lured a young boy under the promise of giving him a puppy. He took the boy to an abandoned house where he assaulted him. The boy survived the attack and Long was then confined to Bridgewater State Hospital. The judge who oversaw the case was bribed by Long's mother, who gave him $30,000 USD to set up a trust. The judge then petitioned the court to parole Long, and he was released in 1935.
Murders
After his release, the judge bought Long a general store in Alton, New Hampshire. Long left Belmont and moved to the state of New Hampshire where he worked as the storekeeper of the general store. It was here that he committed his first murder. In November 1936, Long murdered 10-year-old Armand Nadeau in Dover. The body of Nadeau was found by hunters a month after he'd been murdered, in the cellar of an abandoned house in Rollinsford. Nadeau's skull had been crushed. Long committed his second and final murder on September 10, 1937, in Gilford. Long murdered and sexually assaulted a 10-year-old boy named Mark Neville Jensen from Laconia. Jensen had been walking with his mother's dress in order to return it. He had then disappeared. Witnesses reported seeing Jensen at various towns and cities throughout that day. He was also seen at a restaurant and later was spotted walking with Long and his dog. Jensen's body was found the following night, in a wooded area in Gilford. He had been beaten to death, and his head had been crushed by a screw jack.
Trial and execution
Evidence linked Long to the murder of Jensen, and police arrested him less than a week later. Long then confessed to the murder of Jensen. Further evidence also linked Long to the murder of Nadeau. The trial of Long began on December 6, 1937. On December 13, 1937, Long was found guilty and was sentenced to death. He was originally scheduled for execution on December 30, 1938, but the execution was postponed. Long was executed via hanging just after midnight on July 14, 1939. He was executed in a converted storeroom at the New Hampshire State Prison in Concord. It took seven minutes for Long to die, and the process was described in detail in a newspaper at the time. Long was buried at Pine Grove Cemetery in Manchester, New Hampshire. A paper noted that the only people attending his burial were the cemetery workers. Long remains the last person to be executed in New Hampshire. Before Long's death, the most recent execution in the state was in 1918, when Frederick Small was executed for the murder of his wife. Capital punishment was abolished in New Hampshire on May 30, 2019. This could mean Long will be the last ever person to be executed by the state. However, one person, Michael Addison, still remains on death row in New Hampshire. The abolition law is not retroactive and does not apply to Addison's case, meaning he could still be executed.
