Gardaí are seeking to interview three people in relation to the murder of Andrew Burns who was shot dead outside a church more than two years ago, the Special Criminal Court heard.
Martin Kelly, who is charged with the murder of Mr Burns in Donneyloop in February 2008, made a brief appearance at the court yesterday.
The court heard that "very sensitive information" in relation to the murder investigation was contained in a voluntary interview given by Martin Kelly to two senior policemen in the North.
Superintendent Kevin English told the court that the murder inquiry was "very much alive" and gardaí had a very considerable part yet to complete.
36-year-old Kelly of Barrack Street, Strabane is charged with the murder of 27-year-old Andrew Burns at Donnyloop, Castlefin on February 12, 2008.
Mr Burns was found with gunshot wounds outside a church, by teenagers attending a nearby youth club.
Mr Kelly was charged before the three-judge non-jury court in March of this year, with the unlawful possession of a firearm with intent to endanger life, in connection with the same incident.
Supt English told the court that Kelly was interviewed by gardaí at Letterkenny Garda Station on February 24 this year.
Subsequently he made contact with the PSNI and on March 11 he and Detective Superintendent Diarmuid O' Sullivan interviewed Kelly in the North.
The court agreed to hand over one copy of the transcript of the interview to Kelly's legal team as well as an audio tape and DVD of the interview but specified that no other copies should be made.
Kelly was remanded in custody until July 30 when his case will be mentioned again
