Joseph Lave
From Jack the Ripper Wiki
Informant.
Joseph Lave had recently arrived in England from the USA and was staying temporarily at the International Working Men's Educational Club at 40 Berner Street on the night of Elizabeth Stride's murder. In a statement to the press, he claimed that he had gone into Dutfield's Yard at 12.40am to get a breath of fresh air: "So far as I could see I was out in the street about half an hour, and while I was out nobody came into the yard, nor did I see anybody moving about there in a way to excite my suspicions."[1]
It was so dark in the yard that he had to feel his way along the wall of the club to find his way back in.[2]
