Abberline's suspicions against this guy are too UN-believeable to be believed. There are tens of thousands in London, and he shows up before the murders, leaves afterwards, poisons 3 'wives' which breaks the ripper's MO, and he lived in the same buildings where Martha Tabram was murdered, yet she wasn't a ripper victim. There were scores of other doctors around at the time, and it's not like the murders were happening every day such that you could reasonably measure one's arrival & departure dates from London effectively. If that's the best Abberline had, then either Scotland Yard truly had nowhere else to go with the case, or Abberline was desperate for a suspect.
Seriously, the three official suspects at the time were Geroge Chapman, Michael Ostrog who was in prison at the time of the murders, though his crimes were all theft related, and lastly, Aaron Kosminsky, a polish jew turned 'astrological' believer who was only a suspect because a witness saw him and refused to testify againt a fellow jew, and there were too many differences between the witness discription and Kosminsky, who wandered the streets aimlessly, and was eventually confined back in asylum and died in 1919 with no surgical knowledge or place to take the missing organs such that they'd be unnoticed.
