In a statement released through Liverpool's official website, Cox's family has thanked Merseyside Police for their support, while also confirming that the Irishman is still in need of attention at the Walton Centre in Fazakerley.
"As a family we have been overwhelmed and humbled by the support we have received since Sean was so badly hurt two weeks ago," the statement read. "From the wonderful medical staff at the Walton Centre who continue to care for Sean to the highly dedicated officers of Merseyside Police who have assisted us from the moment we arrived, it has been a great comfort to know that we are in such good hands.
"There are no words to describe the gratitude we feel to the ordinary people of Liverpool and Ireland who have taken Sean to their hearts in a way that underlines why those places have such a deserved reputation for generosity and solidarity. Every day letters and cards arrive from this country, from Ireland and beyond.
"Every one of them wishes us well and the accompanying offers of support have reminded us, even in our darkest moments, that we are not walking alone. Sean remains in a critical condition but he is a fighter and that, coupled with the medical and spiritual support he is receiving, gives us hope in our hearts and we long for the day when our husband, dad and brother returns home to Dunboyne so we can be together as a family once more.
"In the meantime, we would ask that our privacy continues to be respected and when we have news we will share it at the appropriate time. Until then, all we can do is hope and pray for Sean in the knowledge that he is receiving the best possible care."
