Homeless people have told of their shock after a man died in a shop doorway during a night of freezing temperatures.
Essex Police said Mr O’Connor’s death is being treated as unexplained.
Although temperatures in the city dropped below 0C (32F) on the night of his death, his friends say he had been suffering with his health in general.
Mr O’Connor, who was originally from Canada, is understood to have recently undergone an operation for cancer, which required the removal of his voice box.
Ross Miller, who is homeless, said he had known Mr O’Connor for 16 years: “I was devastated when I heard the news. He could be a pain, but he was all right. He was a nice bloke.”
