He lived with a merchant seaman in a fourth-floor walk-up apartment located in San Francisco's Mission District. He later spent six months in San Francisco's VA hospital, and was frequently readmitted into the hospital in 1975, the year he saved Ford's life.

Ford, just emerging from the building, was vulnerable despite heavy security protection. Standing beside Sipple in the crowd was Sara Jane Moore. She was about 40 feet (12 m) away from President Ford when she fired a single shot at him with a revolver, narrowly missing the President.

Sipple said at the time, "I saw [her gun] pointed out there and I grabbed for it. ... I lunged and grabbed the woman's arm and the gun went off." The bullet ricocheted and hit John Ludwig, a 42-year-old taxi driver; he survived. The incident came just three weeks after Lynette Fromme's assassination attempt on Ford.
