Investigation
In questioning, Sarjeant said he had been inspired by the assassination of John Lennon in December 1980, and the attempts on the life of President Ronald Reagan and Pope John Paul II. In particular he noted the ease with which Mark David Chapman had become famous after killing John Lennon. A friend said that at the time of John Hinckley, Jr.'s attempt on the life of President Reagan, Sarjeant had said "I would like to be the first one to take a pot shot at the Queen". The police found that Sarjeant had written "I am going to stun and mystify the world. I will become the most famous teenager in the world." Investigations by psychiatrists found that Sarjeant did not have any abnormalities within the Mental Health Act.
