David Meirhofer was born on June 8, 1949, in
Bozeman, Montana, one of Clifford and Eleanor Meirhofer's five children. Shortly after his birth, the family moved to the small town of
Manhattan, where David would spend his childhood and adolescence. He attended the local Manhattan High School where, due to his melancholic temperament and introverted nature, he was considered an outcast and periodically bullied by other students. After graduating in 1967, Meirhofer worked several odd jobs before being drafted into the
Army in the fall of 1968. He enlisted in the
Marine Corps on October 1, spending the next few months at a military base in
San Diego,
California, as part of the
Signal Corps. After completing his basic training, he was sent to
MCAS Cherry Point, before being dispatched to fight in the
Vietnam War in 1969, serving in the 5th Communications Battalion. For his achievements in deploying communication systems and controlling military formations during armed assaults, he was awarded the
National Defense Service Medal, the
Vietnam Service Medal and the
Vietnam Campaign Medal. In August 1971, he returned to the United States, where he continued his military service at
Marine Corps Base Camp Pendleton. In 1973, Meirhofer was
honorably discharged from the Marine Corps and returned to Manhattan. There he supported himself as a self-employed handyman and carpenter, running a shop in the city. ==Kidnapping of Susan Jaeger, investigation and arrest==
