A former star youth player for Tyrone GAA who was jailed in 2014 for killing his father was released on compassionate grounds to attend his brother's wedding, it has been revealed.
Accompanied by prison guards on Tuesday, Sean Hackett attended the service at St Davog's Church in Dromore before later being escorted back to Hydebank Young Offenders Centre in south Belfast.
In January 2013, aged 18, he shot his 60-year-old father Aloysius Hackett twice in the head in the driveway of the family home in Augher.
While he admitted to the shooting, Hackett denied it was murder.
The court heard he had been suffering from depression in the months before the killing after splitting with his girlfriend.
His original 10-year sentence was later reduced by three years after he appealed on the grounds of diminished responsibility.
New evidence found Hackett had been in a delusional state of mind at the time. He was previously granted compassionate leave to attend the funeral of his father.
The Tyrone GAA boss Mickey Harte has been a consistent supporter of the young man's recovery.
During the trial he referred to him as "a very quiet, unassuming, lovely young gentleman... very warm and very caring".
In 2016 Hackett took legal action against prison authorities, claiming they had failed to provide proper medical treatment for his delusional disorder.
