Paul McCauley murderers 'well known', says Martin McGuinness
The killers of Paul McCauley are "well known in the Derry area", Deputy First Minister Martin McGuinness has claimed.
Mr McGuinness also told the Assembly the attack on the 38-year-old nine years ago was an appalling criminal act.
After lying in a vegetative state since July 2006, Paul died on Saturday from the horrific injuries inflicted on him by a gang of 15.
He was attacked after attending a barbecue with friends and was left with permanent brain damage.
Two other men were also injured in the attack.
Only one person has so far faced the courts in connection with the case.
Sinn Fein MLA Mr McGuinness said it had been "heartbreaking" to listen to Mr McCauley's father Jim say he believed more could have been done in the unionist and loyalist communities to identify the perpetrators.
"He is using language such as, 'It's well known who they are', and, of course, in the Derry area, it is well known who they are," he added. "But the difficulty is that the police - who have been on the record as apologising to the McCauley family, and rightly so - need to be assisted in the renewed murder investigation so that the people who were responsible for the horrendous injuries to Paul, and, ultimately, for his death, can be brought before the courts."
Mr McGuinness also told how he was sure most people in the unionist and loyalist communities were as disgusted at what happened as anyone else.
He said former Assembly speaker William Hay hit the nail on the head when he made it clear that people should be co-operating with the PSNI.
"I want to stress that I think that the vast majority of unionists in the Derry area are as appalled at what happened to Paul McCauley as anybody else," Mr McGuiness said at Question Time.
"But the reality is that there are a tiny minority who were involved in that act and involved in assisting those who were involved in that act."
