man coming under suspicion. As with Kosminski, the asylum case notes say he spoke only Yiddish. The implication is that Kaminsky's syphilis was not cured in May 1888 but in remission, and he began to kill prostitutes as an act of revenge because it had affected his brain. However, Cohen's death certificate makes no mention of syphilis but gives the cause of death as "exhaustion of mania" with phthisis, a then prevalent form of pulmonary tuberculosis, as the secondary cause. Kaminsky might have died as an "unknown" as hundreds of people did each year in the late 19th century. That would account for Fido's inability to find a record of his death in England and Wales during the probable period of his life. Nigel Cawthorne dismissed Cohen as a likely suspect because in the asylum his assaults were undirected, and his behaviour was wild and uncontrolled, whereas the Ripper seemed to attack specifically and quietly. In contrast, former FBI criminal profiler John Douglas said in his 2000 book The Cases That Haunt Us that behavioural clues gathered from the murders all point to a person "known to the police as David Cohen ... or someone very much like him".
