Sister of Lyra McKee, Nichola Corner, sent a message to her sibling’s killer at a peace rally in Derry on Monday.

The rally marked the end of a three-day march from Belfast to Derry in memory of Mckee and was joined by hundreds of people.

The 70-mile walk ended in Guildhall Square where 200 people gathered to hear Corner’s Speech:

“It is my belief that when you went out on the night of the 18 April, you did not intend to turn yourself into a killer.

“Yet the events as they developed led to that becoming your reality. You are now a killer, now the person who killed Lyra McKee, my baby sister, and you cannot take that back.”

Corner vowed to support the killer should they come forward:

“Lyra needs justice and this country demands true peace. I am prepared to be there as you hand yourself in.”

“I promise you here and now that I will meet you at any police station anywhere on this island to support you in taking the brave step to hand yourself in and allowing my sister the justice she deserves.

“I know it will not be easy. That’s why I am reaching out to you because sometimes the right thing is the most difficult.”

She held up the Good Friday Agreement after urging politicians to put an end to continued sectarian violence in Northern Ireland, declaring:

“Together we can end this nightmare because failure is not an option.”

Various people who had been arrested in connection with McKee’s murder including two teenagers and a 57 year-old woman have been released without charge.

The police investigation continues, with the head offices of political republican group Saoradh being searched in connection with McKee’s murder earlier in the month.

Detective Superintendent Jason Murphy has appealed to the public to “come forward and have a conversation with me.”
