Paul McIntyre, 52, denies murdering Ms McKee in Derry’s Creggan estate on Thursday, April 18, last year, possessing a firearm and being a member of the New IRA.
He was originally granted bail by a district judge in Derry but was kept in custody pending the appeal by the PPS.
Today, Friday, March 7, a judge at Belfast High Court overruled the decision to grant bail.
Ms McKee, who was 29, was observing rioting in Derry’s Creggan estate when she was shot on 18 April 2019.
The Public Prosecution Service appealed the decision to grant bail to McIntyre, arguing there was a risk he could commit more offences if he was released.
The High Court judge determined that the risk of re-offending was enough to justify keeping Mr McIntyre in prison.
She said: “The factors outlined by the prosecution are relevant, sufficient and plausible reasons to outweigh the other factors and justify detention.”
McIntyre, from Kinnego Park in Derry, watched Friday’s judgment by video link from Maghaberry prison.
He is currently awaiting trial on charges of rioting on the night Ms McKee was shot dead by the New IRA.
