John "Jack" Gilbert Graham (January 23, 1932 – January 11, 1957) was an American mass murderer who, on November 1, 1955, killed 44 people aboard United Airlines Flight 629 near Longmont, Colorado, using a dynamite time bomb. Graham planted the bomb in his mother's suitcase in an apparent move to murder her and claim $37,500 (equivalent to $430,000 in 2023) worth of life insurance money from policies he purchased in the airport terminal just before the flight departure. Graham was convicted of murdering his mother. He was sentenced to death and was executed by the state of Colorado in January 1957.

John Gilbert Graham was born on January 23, 1932, in Denver, Colorado, the child of Daisie (née Walker) Graham and her second husband, William Graham.^[1] Nicknamed "Jack," Graham was Daisie's second child, as she already had a daughter from her first marriage. Graham was born during the height of the Great Depression, and, in 1937, his father died from pneumonia, causing Daisie to send the young Jack to an orphanage due to their poverty. In 1941, Daisie was married for the third time to Earl King, who died shortly after their marriage. Using her inheritance from King's death, Daisie became a successful businesswoman, but despite her newfound wealth, Daisie did not collect Graham from the orphanage. The two remained estranged until 1954, when Graham was 22 years old, and Daisie King was running a successful restaurant. After their reunion, King and Graham had a poor relationship, and often argued.

In 1955, shortly before the aircraft bombing, King's restaurant was destroyed in a suspicious gas explosion, believed to have been deliberately caused by Graham. Graham had insured the restaurant and collected on the property insurance following the explosion.

Graham married Gloria A. Elson, with whom he had two children, Allen and Suzanne, who were just infants at the time of the notable events. After Graham's execution, Gloria and the two children began using her maiden name. Allen Earl Elson married Denise Marie in 1976 before both went missing on October 16, 1981, while in Curry County;^[2] they are both presumed dead. Gloria died in 1992.^[3]

United Airlines Flight 629 was using a Douglas DC-6B airliner (named "Mainliner Denver") piloted by World War II veteran Lee Hall on the evening of November 1, 1955. The flight had originated at New York City's LaGuardia Airport, making a stop in Chicago before continuing to Denver; it then took off from Denver, Colorado's Stapleton Airfield, bound for Portland, Oregon, with continuing service to Seattle. Minutes after the plane's departure from Denver, the DC-6B exploded, the flaming wreckage falling into farmland near Longmont, Colorado. There were no survivors.^[4]

Graham's mother had been a passenger on Flight 629, and was traveling to Alaska to visit her daughter, Graham's half-sister. At the time, flight insurance could be routinely purchased in vending machines at airports, until changes to the system in the 1980s.^[5][6]

Graham's apparent motive for the bombing was to claim $37,500 (equivalent to $430,000 in 2023) worth of life insurance money from policies he had purchased in the airport terminal just moments before the aircraft's departure.

Investigators discovered that Graham had a criminal record for embezzlement by check forgery, and illegal transport of whiskey for which he had served 60 days in a Texas prison.^[4] King's restaurant had been severely damaged by "a suspicious explosion" earlier that year, and Graham had received the insurance settlement.^[7] Locals also suspected Graham of deliberately causing his new pick-up truck to be struck by a train that year, in order to collect the insurance.^[4][7] After reassembling fragments of the plane, the FBI determined that certain items of luggage in the baggage compartment had contained explosives. Based on that evidence, as well as his contradictory statements, physical evidence found at Graham's house, and finally a confession, Graham was charged with sabotage, then later murder.^[4]

After Graham's arrest, Denver radio station KDEN owner Gene Amole and Rocky Mountain News photographer Morey Engle surreptitiously brought a camera into the jail for an interview of Graham during a reunion with his wife Gloria.^[8] "I loved my mother very much", Graham told Amole. "She meant a lot to me. It's very hard for me to tell exactly how I feel. She left so much of herself behind." When Amole asked him why he confessed, he said the FBI had threatened to point out inconsistencies in statements made by his wife Gloria. "I was not about to let them touch her in any way, shape or form," he said. None of the Denver TV stations would agree to air the film at the time, though it was eventually aired on one of Denver's local PBS stations as part of a documentary.

Graham's confessions gave details about the bomb that matched the evidence from the plane's wreckage. He also told prison doctors that he "realized that there were about 50 or 60 people carried on a DC6, but the number of people to be killed made no difference to me; it could have been a thousand. When their time comes, there is nothing they can do about it."^[4]

Graham's trial led to Colorado becoming the first state to officially sanction the broadcast of criminal trials on television. No federal statute at the time made it a crime to blow up an airplane. Therefore, on the day after Graham's confession, the Colorado district attorney moved to prosecute Graham via the simplest possible route: premeditated murder of a single victim – his mother, Daisie King. Graham recanted his confession, but at his 1956 trial his defense was unable to counter the massive amount of evidence presented by the prosecution. In February 1956, he attempted suicide in his cell, and was thereafter put under 24-hour surveillance.^[4] On May 5, 1956, Graham was convicted of the murder of his mother, Daisie King, and was sentenced to death.

Graham was executed in the Colorado State Penitentiary gas chamber on January 11, 1957. One source has his final words being "Thanks, Warden", after Warden Tinsley patted him on the shoulder. TIME magazine quoted a lengthier statement, "As far as feeling remorse for those people, I don’t. I can’t help it. Everybody pays their way and takes their chances. That’s just the way it goes."^[9]
