John Hinckley Junior, who wounded US President Ronald Reagan and three other people in a 1981 assassination attempt, should be freed after 35 years and released to live with his mother, a federal judge has ruled.
US District Judge Paul Friedman said on Wednesday that Hinckley no longer posed a danger to himself or others and could be released from a government psychiatric hospital in Washington.
Hinckley, 61, "is permitted to reside full-time in Williamsburg, Virginia, on convalescent leave, which shall begin no sooner than Aug. 5, 2016," Judge Friedman said in a 14-page order.
His mother lives in Williamsburg, about 210km south of Washington.
The order includes a requirement that Hinckley meet with his psychiatrist in Washington at least once a month and notify the Secret Service when he travels for the appointment.
A jury found Hinckley not guilty by reason of insanity for the attack on Mr Reagan, which also badly wounded presidential press secretary James Brady. Hinckley carried out the attack in a bid to impress actress Jodie Foster, with whom he was obsessed.
