John Hinckley Jr., who shot and wounded President Ronald Reagan in 1981, was freed from court oversight Wednesday, officially concluding decades of supervision by legal and mental health professionals.

“After 41 years 2 months and 15 days, FREEDOM AT LAST!!!,” he wrote on Twitter shortly after 12 p.m.

The lifting of all restrictions had been expected since late September. US District Judge Paul L. Friedman in Washington said he’d free Hinckley on June 15 if he continued to remain mentally stable in the community in Virginia where he has lived since 2016.

Hinckley, who was acquitted by reason of insanity, spent the decades before that in a Washington mental hospital.

Hinckley’s restrictions were gradually loosened over the years, including the lifting of limits on his social media use. Hinckley’s following on social media has grown to nearly 30,000 followers on Twitter and YouTube over the past several months.

Freedom for Hinckley will include giving a concert — he plays guitar and sings — in Brooklyn, New York, that’s scheduled for July.
